No slips for students at Bristol University

As winter approaches and pathways and steps get slippery with algae and moss that grow fast in wet weather, it’s essential that public spaces are kept clean and algae-free to help prevent slips and falls. With students heading back to begin their studies for the new academic year, the External Estates Team at Bristol University knew it was time to tackle their slippery surfaces.

Vital regular cleaning

We have worked with Bristol University over several years, as their go-to cleaning supplier for external areas such as pathways and courtyards. We encourage our clients to complete regular cleans to both prevent danger and maintain aesthetics.

This season, they contacted us to clean outdoor steps, ramp access and pathways to protect students and staff against safety hazards created by slippery surfaces.

Tackling organic contaminants

When we arrived the surfaces were covered in green algae that had proliferated over the past few wet months before the students returned.

We chose pressurised steam as the best method to remove the organic contaminants, finishing the surface with a biocide to inhibit their regrowth. This keeps the steps and pathways clear for longer, especially in inclement weather.

If you have pathways or steps that are slippery with algae, contact Max or Andy Morris on 0333 234 1445 or email your cleaning enquiry and a member of our team will get back to you as quickly as possible.

Render cleaning: a cost-effective alternative to painting cycles

When one of our existing clients got in touch to ask our advice on an alternative to entirely repainting a residential development, we knew just what would save them time and money.

Breaking the continuous loop of painting cycles

Building managers are often stuck in a continuous loop of painting cycles, trying to maintain a clean and tidy building – but this really isn’t necessary. Many blocks of apartments are rendered with monocouche render that has colour in its pigment, meaning it doesn’t need to be painted. Instead, regular exterior cleaning can leave it looking as good as new and significantly extend the time between painting cycles.

Even if building managers do decide to paint render, it’s important to have the surfaces professionally cleaned first to ensure organic matters like moss and algae that can dislodge the paint are thoroughly removed. That’s where we come in. Exterior building cleaning is incredibly cost effective, at just one third of the cost of repainting. We can entirely clean the exterior of a building with our dedicated equipment to ensure it looks pristine. If that hasn’t quite done the trick, however, the building is then already in the perfect state to be painted.

From the windows to the walls

For Dial Stone Court in Weybridge, Surrey, we embarked on a full project, which included render and brickwork cleaning, window cleaning, gutter maintenance and small repairs. We used steam cleaning to remove dirt, which appeared in patches and streaks across the exterior walls. As part of our gutter maintenance service, we investigated downpipes with a camera on a rod, to check for blockages and potential leaks, then cleared and repaired them.

As the client was so pleased with the result, they asked us to take care of the roof, which had become overgrown with moss. The moss was being swept by wind and rain into the gutters, causing blockages and unsightly stains. We scraped the moss away and used a biocide to penetrate the roof substrate to eliminate the spores to prevent regrowth.

Thanks to our specialist access equipment, including spiders that require very little floor space to operate, we were able to save the client £20,000 on scaffolding costs and caused minimal disruption to residents.

Experts in render cleaning

If you manage a residential or commercial development and want to save money on painting cycles, call Max or Andy Morris on 0333 234 1445 or email your enquiry. We can provide a full exterior cleaning service or carry out isolated cleans on exposed parts of a building to upkeep its appearance and the structural integrity of the exterior surfaces annually or at regular periods, to reduce the need for repainting.

 

Tackling vandalism: cleaning up the mess

In recent months, we’ve responded to a series of vandalism attacks on properties across the country – from Bristol to Leicestershire.

Deliberately damaging or defacing a property is an act of vandalism and is usually targeted against the property owner as part of a protest or the result of grievance. We always aim to respond to callouts as quickly as possible, although of course when it comes to vandalism, the damage is already done. For us, it’s a case of cleaning up the mess as best we can.

Different surface materials require different approaches. The straightforwardness of the job relies on how receptive the surface is to our cleaning processes, whether that’s steam cleaning or non-forceful media blasting.

We are knowledgeable about the products we use and always take a methodical approach, avoiding using chemicals wherever possible – though sometimes this is necessary to remove really stubborn substances to achieve the best result, especially in cases of extreme vandalism.

Bitumen attack in Bristol

In Bristol, we were called to clean a building on an industrial park that had been covered with bitumen. The sticky black substance was thrown across the doors, walls and railings at the front of the property, creating an unsightly mess that would prove very tricky to remove. At the outset, we knew it would be a challenging task, as bitumen is incredibly adherent and notoriously difficult to remove once it has solidified.

It was essential that our client understood the complexity of the job, and we thoroughly explained our approach and the anticipated result to help manage their expectations of the outcome. Using the appropriate tools, we were able to ensure that the doors were cleaned ready to be resprayed and the metal railings and prepped to be repainted.

Our client was delighted with our fast response, the way we dealt with the situation, and the cleaning outcome we achieved – (see images below).

Oil attack in Leicestershire

Previously, we’d received a call to clean a large, multi-million property in Leicestershire constructed in Cotswold-style stone that had been defaced with old motor oil.

It was a sizeable job for our team; oil is one of the hardest substances to remove from porous surfaces as it soaks in and can stain darkly. Again, we explained to the client the extent to which we would be able to clear up the mess, and were careful not to overpromise what could be achieved. They were very satisfied that we were able to achieve a finish that was an 80% improvement. Although some slight staining remained this will eventually weather out.

Paint attack in Taunton

Another job that proved challenging for the team was cleaning a new build in Taunton that had been liberally daubed with paint in a protest attack.

Though not necessarily a difficult material to remove in and of itself, the paint had covered a variety of surfaces – including brick, stone, glass, wood and metal – so it required a number of tools and approaches to clean it off, all of which we were able to provide. We were pleased to be able to leave the property paint-free, and ready for decorators to finish up.

Professional service to clean up defaced surfaces

Defacing a building is a criminal act of vandalism, inconveniencing property owners and tenants, as well as creating a visual eyesore. Whatever substance your building has been vandalised with, we can tackle it with our versatile cleaning methods quickly and efficiently.

To find out more call Max Morris on 0333 234 1445, or email your enquiry and we will get back to you as soon as possible. You can also use our online enquiry form to send details of your project for a quote.

 

K-Rend render cleaning in Portishead

At OneFifty we’ve worked with Jones Building Group on a number of cleaning projects, building a strong working relationship with them over the years.

So, when Jones Building Group needed a reliable exterior building cleaning company to clean the building’s K-rend render, wooden cladding and glass before beginning planned maintenance work, they contacted us.

A streaky situation

The block of flats on Kittiwake Drive in Portishead had become badly marked by algae, moss, lichen and organic growth, causing unsightly streaks, especially on the walls under residents’ balconies.

Large areas of the building had become marked black with algae, making the building’s exterior look unsightly and uncared for. Residents’ balconies had also become affected by organic growth, making the surface slippery and unsafe.

Looking after the residents

Before we started work, the residents were contacted asking them to move any plants and furniture on their balconies out of the way, so nothing was damaged during cleaning. Once we’d safely cleared any remaining items to ensure nothing got broken or damaged the team got to work.

Exterior building cleaning

At the rear of the building we used an all-terrain tracked spider boom to reach the top of the block of flats from the lawned area behind the building, preventing damage to the turf while giving us safe access to clean the top of the building. At the front of the flats we used a boom lift to reach the 16-meter cleaning heights.

As part of our cleaning process we treated the exterior building surfaces with a biocide to make sure all organic growth was effectively removed. This also helps to protect the building’s surface by inhibiting regrowth, so the render stays cleaner for longer. In some areas the team applied several coatings of the biocide to make sure all of the algae was properly removed.

Once all the organic growth had been removed we gave the entire building a final steam clean to ensure a pristine finish.

A proper job

We completed our initial building clean in plenty of time, meaning Jones Building Group could start their maintenance works as planned and stay on schedule for the project.

Once Jones Building Group had finishing their work to the building’s cladding we came back to give the building a final clean, focusing on the glass balcony screens and windows, so the residents had a spotless view of their brilliantly cleaned and maintained building.

Mark Sheffield, Contracts Manager at Jones Building Group says of working with us at Kittiwake Drive:

“We’ve used OneFifty for several years, they’re our go-to supplier for exterior building cleaning. The project at Kittiwake Drive was fairly straightforward and as always OneFifty got the job done with no fuss. They’re very reliable and like Ronseal their exterior building cleaning service does what it says on the tin.”

Major project carried out with minimum fuss

OneFifty was contracted to carry out the external cleaning of a sizeable office building situated in Bristol’s busy business quarter Temple Quay.

The exterior surfaces included metal clad pillars, stone lintels, 6 separate corrugated roof areas and an outdoor top-floor terrace. We also cleaned the external pathways, entrance ramps, front steps and a large domed area of block paving outside the front entrance of the building.

We love a challenge!

This was a sizeable project; the building is six storeys high with a foot print of around 2,500 square metres. The location, height and structure of the building all presented different challenges – aside from a pretty tight deadline!

We used tracked and truck-mounted cherry pickers to achieve the required height and a vertical out-reach of up to 32 metres, then rope access to get up close to some of the harder to reach surfaces of the building façade. This combination allowed our operators to reach and clean every last inch of the building exterior, achieving fantastic results for our client. They also worked flat out over 14 consecutive days to complete the task within the required time frame.

Meeting all Health and Safety requirements

Health and safety is always critical in our line of work and it was of paramount importance on this project.

Temple Quay is a busy area and the building is surrounded by pedestrian walkways. Being experienced in working in public spaces our team can minimise any inconvenience to passers-by and our flexible working hours mean we can work out of hours to help reduce disruption.

OneFifty’s experienced operators are IPAF and IRATA trained and we follow tried and tested procedures that support safe working. We also have all the necessary insurances in place – so that our clients can have complete peace of mind.

Reduce damage caused by dirt and algae  

Cleaning the building exterior not only makes the building look great, it also helps preserve the materials and the structure of the building, warding off costly repairs. Cladding can fail if not properly maintained, so regular cleaning is important. On this building some of the metal cladding had begun to oxidise so we used a special cleaning agent to remove the oxidation, then applied a wax covering to protect the surface and improve its appearance.

Being in the city centre (and near a train station) many of the external surfaces of the building had become badly stained by environmental pollution, others had been colonised by algae. We used pressurised steam at 150 degrees to remove these pollutants quickly and effectively. We also treated relevant surfaces with an algae inhibitor to discourage regrowth. While we had the access equipment in place we also arranged for the windows to be cleaned so that the whole building was left looking clean and shining like new.

Fast graffiti removal for Environment Agency

In December 2018 a group of climate change protesters carried out a protest in Bristol which included a graffiti attack on Horizon House, the regional HQ for the Environment Agency.

Slogans and the distinctive X-shaped symbol of the Extinction Rebellion protest group had been spray painted all over the building including the glass frontage (doors and windows) and the stone work.

Rapid response

We received a call for help from the managing agents at around 2:00pm on a Saturday afternoon and they were very keen to get the graffiti removed as quickly as possible.

On this occasion we were able to offer a super-fast response. We had a vehicle and team of operators on the scene by 3:00pm that afternoon and had completed the clean up by 5:00pm. Our system is vehicle-mounted, fully self-contained and delivers the most efficient and effective exterior cleaning on the market in the UK.

With everything we needed to hand, our operators were able to remove the graffiti and leave the building facade looking completely clean – as if nothing had ever happened. Our client was delighted both by the speed of our response and the quality of our cleaning.

Rapid removal helps avoid proliferation

Unwanted graffiti is a massive blight – especially an attack as significant as this. For the Environment Agency it made absolute sense to get it cleaned off as quickly as possible. But even with smaller attacks – such as a single tag on a building – it makes sense to get it cleaned up as soon as possible, otherwise you are likely to attract copycat attacks.

On numerous occasions we have quoted to remove a tag from a building and by the time we have been given the go ahead and arrived at the scene to clean it off – there are more tags.

So, no matter what size the job, if you need help to remove unwanted graffiti contact Max or Andy Morris on 0333 234 1445 or email your enquiry and we will get back to you as quickly as possible.

We can do it when we B&Q it

There is kudos in working for a big, well-known brand so we were pretty chuffed when B&Q got in touch and asked us to clean their store at Imperial Park, Bristol.

One of the main challenges of cleaning the façade of a busy major retail store is that work must be done out of hours to avoid interfering with customers’ shopping times. That is no problem for our crew, we are used to extremely early starts and late night finishes. Also, with our fully self-contained Trailerjet XL system we don’t need access to mains services – we can literally turn up, plug in and get on with the job.

Using our heads!

Working at night does require good lighting to enable us to see what we are doing and make sure that any difficult staining is removed. We had originally planned on flood lighting the project with huge outdoor angled lights. On this occasion however we found that the lights were creating too many shadows, making it hard to clearly judge how the cleaning was progressing. So we used our heads – and I mean that quite literally in that we switched to using super powerful, head-mounted torches that gave a far better, more focussed light. This allowed us to ensure that the cleaning was done to a consistently high standard across the whole building exterior and that nothing was missed.

The huge store was cleaned over two weekend nights and on both nights everything was cleared up and packed away ready for the store to open the next morning. There was no interruption to business, no hassle – just a brilliant, shiny clean building exterior and another very satisfied client!
