Facade sealing in Wanborough
Facade sealants sit in the sun, rain and frost every day, and they wear out over time. How long a joint lasts depends on the movement it takes, its exposure, the product and how well it was installed. When the time comes, we cut the old sealant out completely and start again. Site teams most often ask us about cladding panel joints that have opened up and unsightly perimeter sealant on a visible elevation, on shopfront frames, perimeter joints where frames meet the structure and window and door perimeters. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Wanborough, preparation and product choice get the time they need.
Construction in and around smaller places such as Wanborough is often barn conversions, small groups of houses or extensions to halls and schools. Each still needs a proper mastic package: window perimeters, facade joints and internal sealant to the specification.
We stand by our work with a 12-month guarantee. That covers our preparation and application, and we come back if anything isn’t right.

What we are called out for in Wanborough
When the sealant tears down its centre, it has normally been asked to move more than it can. Too thin a bead, too narrow a joint or a product with the wrong movement class are common reasons.
Clients normally get in touch after noticing one or more of the following:
- Failed seals around shopfront and entrance frames
- Perimeter sealant that has split or peeled away
- Leaks at window and door perimeters
- Cladding panel joints that have opened up
When a school such as Puttenham CofE Infant School is extended or refurbished, the mastic package is often squeezed into the holidays.

Common questions from Wanborough clients
Could you schedule work at a campus like University of Surrey - Manor Park Campus for the vacation?
Yes, holiday working periods are the norm on campus jobs. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.
Is Wanborough off your patch?
No. Places such as Wanborough are covered as much as the big towns. London and every South East county are within our area. Send photos and a list of what needs doing, and we will plan the job to need as few trips as possible.
Can you work to our specification?
Yes. We follow the specification, along with the manufacturer’s installation guidance, and any queries are raised before we start.
What site paperwork can you supply?
Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we will confirm them with the quote.
What’s the quickest route to a quote?
It works in four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. Step one needs little more than photographs and a postcode.
Can you just add new sealant on top?
No. New sealant won’t hold on old sealant, so the old bead is cut away. That is what makes the new joint last.
Do you use silicone for external joints?
It depends on the joint, the substrate and any specification. BS EN 15651 Parts 1 and 2 cover facade and glazing sealants, and specifications often name them and we follow the specified product.
Diagnose, treat, sign off
A typical day starts with protection: tape along each joint edge and covers over finishes, stock and equipment close by. On site, the work usually takes a day or two for a few elevations, and longer where access has to be moved around the building, and our waste is bagged and taken away as we go. Smaller jobs around Wanborough can be grouped with others nearby, which keeps travel down. You’ll have a fixed quote before work starts.
- Access, site rules and timing are settled with the client up front.
- Weather and temperature are checked against the product’s limits.
- Each joint is cut out and the edges inspected.

- For older buildings, check the asbestos register before work

- Leaks from roofs, gutters or failed flashings rather than sealant joints
- Damaged frames that need replacing
- Work on the window or framing system itself
If in doubt, call 01277 525 020 or send details through our quote form and we’ll say what we think.

Facade sealing in Wanborough: the local picture
At about 31 miles from central London, Wanborough is within reach of the capital. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, and each scheme needs its mastic sealed to programme. Rainfall across the South East, Wanborough included, is lower than in many parts of the UK. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, so the external programme keeps a little slack.
With historic properties like Wanborough Manor, 0.1 miles to the east of Wanborough, in the area, refurbishment work often meets old masonry that needs compatible sealants. Hospital estates such as Royal Surrey County Hospital, 2.5 miles east of Wanborough, tend to grow and change in phases, often next to occupied wards, so facade and perimeter sealing has to fit the estates team’s plan.
Wanborough is about 4 miles west of Guildford, in Surrey. Businesses, contractors and managing agents in Wanborough can call on us for facade joints. We work across 379 places in Surrey, from busy centres to rural villages. There’s a separate page for Reading, roughly 20 miles from Wanborough.

Why deal with it now?
Topping up a failed joint normally buys very little time. A full cut-out and fresh bead is the repair that holds, so you aren’t paying for the same joint twice. Converted and older buildings near places like Wanborough tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.
What a job costs comes down to the quantity of joints, how much old material needs removing and the access. Call for a quote when you are ready.

Keeping the joints sound
Every sealant joint needs some looking after, and how long they last depends on how they’re treated. We suggest:
- Avoid patch repairs on failed facade joints
- Check that rainwater leaves the facade the way it was designed to
- Don’t wait for a second leak before calling
- Check the asbestos register before old mastic is disturbed
Look at perimeter and panel joints as part of routine building checks. Watch for splits, gaps at the edges, hardening and discolouration; note where they appear.
Building facade joints into a maintenance cycle avoids emergency repairs. Regular checks let you renew joints before water gets in, rather than waiting for a ceiling stain.
