About our construction mastic in Great Hollands
Since 2005 we have worked alongside main contractors, developers and fit-out firms. Quantities come off the drawings, the sequence is agreed with the site manager and the work follows the trades. To price a package in Great Hollands, send drawings and the specification through our quote form. Most enquiries involve sealant knocked or painted over by other trades and early adhesion failures on new external joints, across internal decorators’ caulk, cladding and panel joints and window and door perimeters. Facilities teams, main contractors and managing agents in Great Hollands tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
On a small site around Great Hollands, the mastic is best done in the fewest visits we can manage. Tell us when scaffold comes down and when decoration finishes, and we will plan around those stages.
What our 12-month guarantee covers is the way we did the job: 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?
It helps to bring the mastic subcontractor in before the package is urgent. Early involvement means gaps, products and access are sorted before the programme bites rather than at the snagging stage. Called in at the end, the same issues surface during handover. A failed joint lets water into a building whatever its size. Early resealing avoids the damage that follows a leak.
The specified product makes a difference, as does the preparation each joint needs, such as cutting out, priming or new backing rod. Access, phasing and site requirements come into it too.

Contractors’ notes for Great Hollands
Great Hollands is in the South East, one of the UK’s drier regions. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, which is why external dates are agreed with the site manager. Great Hollands sits in or beside Bracknell, a twentieth-century planned town. Regeneration of planned-town buildings brings recladding and replacement windows, each with joints to seal.
Work at a hotel such as Easthampstead Park Hotel (0.8 miles west of Great Hollands) tends to be programmed around bookings, mastic included. On a healthcare site such as Broadmoor Hospital, 2.1 miles to the south of Great Hollands, new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully.

What we are called out for in Great Hollands
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.
These are often picked up first by site or facilities staff:
- Existing joints on a refurb that need cutting out and resealing
- Perimeter gaps outside the sealant’s range
- Early adhesion failures on new external joints
- Snag items on joints that need redoing before handover
School extensions, at buildings such as Great Hollands Primary School, normally run to the summer holidays, mastic included.
Questions to ask before you book
- What site paperwork they can supply

How do I request a quote?
The quote form is the simplest route, though you can also call 01277 525 020 or email us. Photos, drawings or a joint schedule help us quote quickly.
Is the mastic package guaranteed?
The work is guaranteed for 12 months. Keeping other trades off finished joints prevents most problems.
Do you do fire-rated sealing on new builds?
It can be part of the package where specified. Record requirements are confirmed at quote stage.
Will you stick to the specified products?
We work to the specification and the manufacturer’s installation guidance. Primers, backing and joint depth follow what the manufacturer sets out.
Doing it in-house
What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.
General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.
Surface by surface
Snagging before handover
Snagging is often the final mastic stage. We can work through the snag list area by area and damaged joints are redone rather than patched.
External facade and movement joints
Movement joints in the facade are sealed with a product suited to the expected movement. Depth is controlled with backing rod so the bead bonds to two sides only.
Diagnose, treat, sign off
Diagnose, treat, sign off: every visit follows that pattern. First comes an inspection and agreement on scope, then the work is carried out to the specified product and detail, and we finish with a walk round so the work can be signed off.
