Construction mastic across Windsor and Maidenhead: what to expect
Most of the packages we price run well beyond frames: external door and window perimeters, internal decorators’ caulk where specified, sanitary joints in bathrooms and washrooms, kitchen worktops and splashbacks, and snagging before handover. Splitting those between trades often leaves gaps in responsibility, and one applicator team gives a consistent finish. We work on brick and block movement joints, internal decorators’ caulk and window and door perimeters, and the failures we are asked to look at most are missed perimeter joints on a new elevation and inconsistent sealant finishes from plot to plot.
We schedule the visit to fit the site hours and access windows you give us. While we’re working, the area stays contained and tidy, and your contact hears from us before we move to the next area.
- We walk the site or review drawings to understand the package.
- You receive a fixed quote covering scope, products and sequence.
- Paperwork is agreed and applicators are inducted on site.
- Sealing follows the programme as areas are released.
- Problems we find, such as oversized gaps, are raised right away.
- Final snagging is completed and the 12-month guarantee applies.

Building work around Windsor and Maidenhead
Across Windsor and Maidenhead, including Maidenhead, Windsor and Boyn Hill, construction ranges from housing and schools to offices, units and refurbishments. Window and door perimeters, facade and cladding joints and internal sealant are sealed to the specification and the programme.
The South East is one of the UK’s drier regions, though outside work in Windsor and Maidenhead still waits for dry faces, and cold mornings bring frost and condensation on steel and glass.
Maidenhead: For contractors at a school such as Claires Court Schools, sealing has to be finished before term starts. New wings at hospitals like St Mark's Hospital (to the north-west of Maidenhead) bring long runs of window and panel joints to seal.

Your fixed quote is built from the real scope. It takes account of:
- Specialist products, such as fire-rated or hygienic sealants
- Backing rod, priming and other preparation

Common problems we fix in Windsor and Maidenhead
A new building moves while it dries and settles. Plaster, screeds, timber and blockwork all shrink as they lose moisture, which opens up internal joints, particularly where caulk has been used in a joint that moves. Picking a flexible sealant where there’s movement keeps snags down.
Look out for the following:
- Frame gaps too wide for sealant alone
- Missed perimeter joints on a new elevation
- New external sealant already peeling away
- Internal caulk splitting as the building dries out
Different surfaces, different methods
Snagging before handover
Snags normally come from damage by following trades, missed joints or poor earlier work. Snagging can be included or priced separately, depending on what suits the programme.
Bathrooms, en suites and washrooms
Sanitary joints around baths, showers, basins and WCs need anti-mould sanitary silicone. Each joint is prepared, sealed and finished with a neat tooled line, and any bath is loaded with water first where that’s the agreed method.
Why deal with it now?
A quick bead over a damaged joint can get an area past inspection, but it rarely lasts. Sealant can’t grip a contaminated or existing bead. Damaged joints are removed and resealed from clean faces.
What your quote should include
- Whether their applicators hold CSCS cards
- Do they follow the manufacturer’s priming guidance?
- How the existing material will be dealt with
- What site paperwork they can supply
Should maintenance staff do it?
Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
Questions we are asked in Windsor and Maidenhead
Will you just go over the old sealant?
No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.
How do you work with the site programme?
We seal plot by plot or floor by floor as areas are released. The sequence is agreed with the site manager at the start and updated as the programme moves.
Are you CHAS accredited?
We are CHAS accredited and a Constructionline member, with CSCS-carded applicators. We are also fully insured, with five million pounds of public liability cover.
How long does a typical visit take?
The duration is planned around your programme and the access we’re given. We’ll give you an estimate of time on site when we quote.
What happens if the weather stops external sealing?
External sealing goes ahead only with a dry joint inside the product’s temperature range. Wet or cold joints cause adhesion problems so it’s better to wait.
Do you take on multi-site work?
Yes. A group of buildings can go on one quote, with one point of contact across South East England, Greater London and Scotland.
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.
