Facade sealing for businesses in Datchet
Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.
On site: what to expect
At the end of each section, the masking comes off, the area is cleaned and every joint is checked. Where the sealant needs time to cure before use, we tell you and sign the area. What matters most for a job in Datchet is a clear list of what needs doing. You will then get a fixed price for the work.
- We look at the joints, the drawings and the access before pricing.
- The old bead is cut away completely, not overlaid.
- Both faces are cleaned and, where the product needs it, primed.
- Closed-cell rod fixes the depth, and the sealant grips two sides only.
- A facade-grade sealant rated for the movement goes in, tooled to a concave profile.
- The completed runs are checked with you, then the 12-month guarantee applies.
Before we start on site
- Tell us what induction or permit system the site runs
- Explain the parking and delivery arrangements
- Have the specification and drawings to hand

Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price against exactly what is specified. For smaller jobs, photographs and a description will do.
Advice
Facade sealing in Datchet, done properly
Most facade joint failures trace back to the joint, not just the sealant. Joint width needs to match how far the joint moves and how far the sealant can stretch, and closed-cell rod sets the depth, keeping the bond to two faces, often at around 2:1 width to depth, as the manufacturer advises. If you have old perimeter mastic that has dried out and draughts around frames and panels, we can help, whatever the surface. For commercial sealant work in Datchet, you deal with one contact from quote to sign-off, whether it’s one building or several.
Building work in places the size of Datchet is typically small-scale: a handful of new houses, barn conversions, a school or hall extension. Even a small site needs its perimeter and facade joints sized, backed and sealed properly.
The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Questions about Datchet
Will you plan work around the academic year at somewhere like Royal Holloway University?
Yes. We plan campus work around teaching, exams and residence turnarounds. We are CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.
Is a hospital such as Princess Margaret Hospital somewhere you can work?
Yes. Healthcare sites are among the places we work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
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.
Can you follow the specification on our project?
Yes. Send it with your enquiry, and the quote will be based on it.
When can the area be used after sealing?
Curing time varies by product, and we confirm it on the day, and sign any area that should be left alone.
Should we check old sealant for asbestos?
Some older mastics, especially in pre-2000 buildings, can contain asbestos. The dutyholder’s asbestos register should be checked first; if it’s suspected, work stops until it has been tested. Removal of asbestos isn’t something we do.
When can you be on site?
The office is staffed Monday to Friday, from 8am until 5pm. Tell us your site hours and access windows and the work will be fitted around them.
New build and refits around Datchet
The South East is one of the drier parts of the UK. Even so, frost and condensation on steel and glass are common on winter mornings, so external mastic is timed for workable conditions and agreed with the site manager. Datchet has plenty of hotels close by, all within 2 miles. Hotel schemes tend to have fixed reopening dates, so the mastic is programmed tightly with the other trades.
For a contractor working at a hospital such as Princess Margaret Hospital, 1.6 miles to the south-west of Datchet, perimeter and facade sealing is planned around patients and deliveries. When a college such as Windsor College, 1.6 miles to the west of Datchet, builds or refurbishes, the mastic package typically has to fit around students and staff.
Datchet is about 2 miles east of Windsor, in Windsor and Maidenhead. Anywhere in SL3, it works the same way: send details, get a fixed quote, we seal, and the work is guaranteed. Our Windsor and Maidenhead coverage takes in 60 places, large and small. Reading is covered too, some 17 miles away.
We cover the SL3 postcode districts. Streets here include High Street, London Road and Percy Place, and sites on any of them can send details for a fixed quote. If your building is just outside Datchet, we cover Ditton (1 mile north-east), Myrke (1 mile north-west), Sunnymeads (1 mile south-east), Brands Hill (2 miles east) and Old Windsor (2 miles south). A short drive away, we cover Maidenhead (7 miles west), Boyn Hill (7 miles west), Cookham (8 miles north-west), Furze Platt (8 miles north-west), Dedworth (3 miles west) and Broomhall (7 miles south). Datchet ranks among the main centres of Windsor and Maidenhead, with offices, shops, schools and other public and commercial buildings, and we cover them all.

What else we do in Datchet
Common problems we fix in Datchet
When the sealant tears down its centre, it has usually been asked to move more than it can. The joint may be too narrow, the bead too thin or the sealant the wrong movement class.
Typical triggers for a call:
- Staining on stone next to old sealant
- Water coming in around window frames
- Cladding panel joints that have opened up
- New sealant peeling off old mastic
On a campus such as Royal Holloway University, 4 miles south of Datchet, new teaching buildings and residences are normally built and refurbished around the academic year.
What your quote should include
- Who will actually carry out the work
- Their plan for phasing and protecting the area
- Do they follow the manufacturer’s priming guidance?
- Health and safety accreditation such as CHAS
Cost factors for facade joints
Each job is priced on its own details. The main factors are:
- Travel to remote or island sites
- Specialist products, such as fire-rated or hygienic sealants
- Phasing around occupants
- Quantities, in metres or numbers
There’s no price list, because the scope varies so much from one building to the next. Call for a quote and we will price your job on its own details.
What we need to price the job
The more we know, the firmer the quote. Helpful details to send:
- How the joints are reached, and at what height
- What the building is and how it’s used
- Any dates the work must fit around
- The asbestos register, for older buildings
A good quote starts with a clear picture: the joints involved, quantities, access and the product called for. Send what you have, and we’ll arrange a site visit if anything is unclear.
Leave it or put it right?
Every shower drives water through a split perimeter bead. The damage builds out of sight: wet linings, rusting fixings, staining and spoiled finishes. Resealing early costs far less than repairing what the water reaches. Sealant hardens, cracks and loses grip with age, UV and movement. Renewing it in good time keeps the building weathertight.
Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you will have a fixed figure to work with.

Surface by surface
Window and door perimeters
Perimeter joints move as frames expand and contract in the sun. The rod limits depth, leaving the bead able to flex as the frame moves.
Perimeter joints at frames and structure
Where framed systems such as shopfronts meet the building structure, there is a perimeter joint to seal. We seal those perimeter joints rather than the system it surrounds.
