Construction mastic for commercial buildings in Great Tew
Refurbishment work needs a slightly different approach from new build. Old beads come out completely, as fresh silicone can’t grip old. After that, the joints are prepared and sealed to the specification. If you have window and door perimeters that won’t pass inspection and early adhesion failures on new external joints, we can help, on floor and skirting junctions, cladding and panel joints and window and door perimeters alike. Whoever orders the work in Great Tew, the brief is normally the same: a clear scope, tidy work and joints that don’t fail again.
For a site near Great Tew, the mastic visit is planned so the right sealants, primers and backing rod are on hand, timed to the stage the job has reached. Drawings, photographs and the programme let us give a fixed quote.
We stand behind the joints we seal: 12 months, guaranteed. That covers our preparation and application, and if something we did falls short, we return to it.

Site staff or a sealant specialist?
Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.
The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.
Surface by surface
Bathrooms, en suites and washrooms
On multi-unit schemes, consistency matters across hundreds of bathrooms. A single team keeps the standard consistent.
External facade and movement joints
External movement joints often need primer, depending on the substrate. Primer goes on where the sealant maker calls for it.
Looking after the joints
To get the most from the new sealant:
- Brief the final clean team to avoid blades near sealant
- Share drawings and the specification as soon as possible
- Note which sealant went where at handover
- Flag uneven or tapered frame gaps early
At handover, keep the product details with the O&M information. Future maintenance is easier when the products are known, and tells you what to reseal with. Tell us what records you need and we will confirm with the quote.
Snag items left to the last week put handover at risk. Clearing snags area by area spreads the work out.
Why deal with it now?
Leaving mastic to whichever trade is fitting the element can look cheaper on paper. In practice it often means different standards, gaps in responsibility and snags nobody owns. One mastic subcontractor for the lot keeps it simple. Halls, stores and units around places like Great Tew may not be checked every day, so a failed joint can leak for a while before anyone sees it. Resealing early avoids that.
The price depends on the quantity of joints, what has to come out first and how the joints are reached. Call for a quote when you’re ready.

Sites and facades in and around Great Tew
Great Tew sits in one of the drier corners of the country, the South East. Even so, frost and condensation on steel and glass are common on winter mornings, so we time external mastic for dry faces and agree it with the site team. Great Tew is about 65 miles from central London. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, and each scheme needs its mastic sealed to programme.
When units on a site such as Enstone Airfield Industrial Estate, 2.2 miles south of Great Tew, are refurbished or reclad, the panel joints and window perimeters are part of the mastic package.

Common questions from Great Tew clients
Can you keep pace with our programme in Great Tew?
Yes, we work to the programme and the sequence the site sets. Let us know which documents your site asks for, and we will confirm them alongside the quote.
Is Great Tew too small for you to travel to?
No. Places such as Great Tew are covered as much as the big towns. We cover Greater London and the counties of the South East. Where we can, we group nearby jobs to make the most of each trip.
What joints do you seal on a new build?
External and internal frame perimeters, caulking where it’s specified, sanitary silicone, kitchen joints and snagging before handover. The scope follows your specification.
How long do sealant joints last?
It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.
Will you stick to the specified products?
Specification first, then the maker’s instructions. Primers, backing and joint depth follow what the manufacturer sets out.
What happens if the weather stops external sealing?
External sealant needs a dry joint and a temperature within the product’s range. Damp, frost or condensation on frames can stop work so we typically switch to internal work when that happens.
What if there’s asbestos in the old mastic?
Some older mastics, especially in pre-2000 buildings, can contain asbestos. We check the asbestos register before cutting out old sealant in an older building, and work stops until any suspect material has been tested. We don’t remove asbestos-containing materials.
Signs you need construction mastic in Great Tew
Three-sided adhesion is a frequent fault on new work. Fixed to three faces, the sealant rips the first time the joint opens, so depth is controlled with backing rod or bond-breaker tape.
These are often picked up first by site or facilities staff:
- Old sealant on a refurbishment that needs stripping before new work
- Frame perimeters left unsealed or poorly sealed
- A mastic package split between trades with no clear owner
- External joints sealed in damp or cold conditions that are now failing
When a school such as Great Tew County Primary School is extended or refurbished, the mastic package is often squeezed into the holidays.
What to look for in a quote
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
- What site paperwork they can supply
- The named product and why it was chosen
- Whether their applicators hold CSCS cards
