About our mastic sealing in Windlesham
Before work starts, most agents and landlords want the documents in order. For documents, tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote. We’re a Constructionline member and CHAS accredited, and we carry public liability insurance. If you have no planned programme for sealant and draught complaints from residents or tenants, we can put it right, whatever the surface. For commercial sealant work in Windlesham, you deal with one contact from quote to sign-off, whether it’s one building or several.
Older buildings and conversions around places like Windlesham mix old masonry with newer frames. Perimeter joints need a sealant that suits both frame and masonry.
The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Leave it or put it right?
Piecemeal repairs over the years often leave mismatched sealant. A block-wide reseal gives one product, one colour and one guarantee. For buildings in places like Windlesham, one well-planned visit beats several small ones, so it’s worth dealing with every failing joint at once.
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 we will put a fixed figure on it.
Why us?
- One contact handling all your sites
- Public liability insurance in place
- Standard and matched colours in many product ranges
- Clear, fixed quotes

From enquiry to sign-off
Before we leave any area, we remove the tape, clean down and inspect every joint. If an area should be left alone while the sealant cures, we say how long and put signs out. For a site in Windlesham, we plan so the whole job is done in one go where possible. Photos with rough sizes let us arrive with everything needed.
- First we look at the mastic on each building and note what needs replacing.
- We send a fixed quote that sets out the joints, the products and the programme.
- The programme is fixed with you, including dates you can pass on to residents or tenants.
- Old sealant is stripped and each face prepared back to firm material.
- Deep joints get backing rod, faces are primed if the manufacturer specifies it, then the joint is sealed and tooled.
- Completed joints are inspected and carry a 12-month workmanship guarantee.
Preparing the site
- Arrange parking or a loading space
- Share your working hours and any access restrictions
- Send asbestos survey details if the building is pre-2000

What else we do in Windlesham
Planned mastic for Windlesham portfolios
Windlesham sits in one of the drier corners of the country, the South East. Outside mastic still needs a dry joint and the right temperature, and south- and west-facing elevations, which take the most sun and rain, often age first. Windlesham lies roughly 26 miles out from central London. Within reach of London, blocks run by agents and associations are common around stations.
Owners of student blocks near Imperial College Silwood Park Campus, 3.1 miles to the north of Windlesham, can schedule frame and external mastic for the summer vacation. For agents with blocks near Bagshot station, 1.4 miles west of Windlesham, a block-wide mastic programme deals with frames, balconies and entrances in one go. Trustees of buildings like Church of St John the Baptist can bring frame and external mastic into a planned maintenance list.
Windlesham is about 4 miles north-east of Camberley, in Surrey. We cover Windlesham, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. Our Surrey coverage takes in 379 places. For work in that direction, see our Reading page (15 miles or so).

Surface by surface
Estate-wide resealing programmes
Housing associations and agents often manage many similar blocks. We quote building by building and work through them in turn.
Planned maintenance
How long mastic lasts depends on exposure, movement and the product used. Regular inspection is the best way to plan resealing.
Questions we are asked in Windlesham
Is Ascot Business Park, near Windlesham, within your area?
Yes. Estates, retail parks and business parks around Windlesham, Ascot Business Park among them, are all within reach. A few photos and the unit address let us price the work.
Is a smaller place like Windlesham outside your area?
No. Places such as Windlesham are covered as much as the big towns. London and every South East county are within our area. Where we can, we group nearby jobs to make the most of each trip.
Can you plan resealing across several buildings?
Yes, planned programmes suit estates and portfolios. The quote can be split however suits your budgeting.
Will you just go over the old sealant?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.
Who decides which product is used?
Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
Will you come and look before quoting?
Many jobs can be quoted from photographs, drawings or a joint schedule. If the job needs a look first, we’ll arrange a visit before quoting.
How soon can the area be used again?
The product and site conditions decide that. Some products skin over quickly but need longer to cure fully, so we will confirm the curing time on the day.
When to bring in a specialist
What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.
Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong usually costs more in the end than doing them right.
Commercial clients in Windlesham
We work for building owners and managing agents on sealant work across single buildings or whole portfolios around Windlesham. One quote can cover more than one site, so there’s one set of paperwork to deal with.
Main contractors use us as their sealant subcontractor. We work to your programme, your specification and your site rules.
Quoting for work in Windlesham
Each job is priced on its own details. The main factors are:
- The product specified
- How much there is to seal
- Induction, permit and paperwork requirements
- Access and working height
Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.
Details that help us quote
It doesn’t need to be a full survey. These details are enough to start:
- How the joints are reached, and at what height
- Whether the building will be occupied during the work
- Drawings or a marked-up plan, if available
- Photos of the joints, close up and from further back
If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price against exactly what is specified. For smaller jobs, photos and a description will do.
