Construction mastic in Bracknell
On refurbishments, the mastic package normally includes cutting out old sealant as well as sealing new work. Old beads come out completely, as fresh silicone can’t grip old. New and existing joints then get the same preparation. We work on window and door perimeters, floor and skirting junctions and sanitary and kitchen joints, and what we are called in for most is early adhesion failures on new external joints and perimeter gaps outside the sealant’s range. Whoever orders the work in Bracknell, the brief is typically the same: a clear scope, tidy work and joints that don’t fail again.
Bigger sites around a town like Bracknell usually want mastic phased by plot, block or floor. CSCS-carded applicators work to the site’s rules and the specification, and any snags are cleared before handover.
A 12-month guarantee applies to all our work. Should something we installed fail, speak to us on 01277 525 020 or send details through our quote form and we will come back to it.

What we can’t put right
A few problems need another trade or a different fix, and we point that out rather than sealing over them:
- Joint design decisions that belong to the architect or engineer
- Deciding which fire-stopping product a penetration needs
- Faulty frames rather than failed sealant
Not sure which it is? You can call 01277 525 020 or email a schedule or drawings and we will tell you honestly before you book.

Our process
We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. Then we strip out anything that has failed, prepare every joint and seal it. Town-centre jobs in Bracknell can mean limited parking and loading, while out-of-town estates typically have yards and car parks. Let us know what’s there when you send details.
- 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.
- Any frame gaps or issues outside our scope are flagged to the site team.
- The package is closed out, snags cleared and backed by our 12-month guarantee.
Getting the site ready
- Send your site hours and access windows
- Tell us what induction or permit system the site runs
- Arrange parking or a loading space
Getting a fixed quote
Every job follows the same four steps: send details, get a quote, we seal, guaranteed. The first step is to call 01277 525 020 or email drawings and photos with what you know.

What the job involves on each surface
Bathrooms, en suites and washrooms
On multi-unit schemes, consistency matters across hundreds of bathrooms. One applicator team gives the same finish everywhere, plot by plot or floor by floor.
Window and door perimeters
A frame gap that’s too wide can’t just be filled with sealant. We check them during the first walk-round and flag any that need packing or adjusting before sealing starts.

Quoting for work in Bracknell
The price varies from site to site. Expect it to depend on:
- The site’s rules and procedures
- How much there is to seal
- Distance, for remote addresses
- The product specified
We don’t publish prices, 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.
Before you send an enquiry
To price the job accurately, we need to understand the site. Send us:
- The postcode of the building
- The type of building and who uses it
- Specification clauses that apply
- Whether an asbestos survey exists
Every quote starts with the facts: what’s there, how much of it, how we reach it and what’s specified. Send what you have, and we will arrange a site visit if anything is unclear.
What we are called out for in Bracknell
Three-sided adhesion is a frequent fault on new work. Bonded to the base of the joint and both sides, sealant can’t stretch evenly.
Look out for the following:
- Bath and shower joints scraped during the final clean
- Failed sealant in an existing building being refurbished
- Perimeter gaps outside the sealant’s range
- Different trades sealing to different standards
Further education sites such as Newbold College of Higher Education, 1.7 miles north-west of Bracknell, are extended and refurbished from time to time, with mastic often programmed into the summer break.
What to look for in a quote
- What site paperwork they can supply
- Whether their applicators hold CSCS cards
- Their pre-qualification and accreditations
- Do they follow the manufacturer’s priming guidance?
