Honest limits
We check first that sealant really is the fix. It isn’t the answer for:
- Rework caused by others damaging completed areas
- Frames fitted out of tolerance
- Fire-stopping design or sign-off (that’s for the designer, fire engineer and building control)
Not sure which it is? You can ring 01277 525 020 or email a schedule or drawings and we’ll tell you honestly before you book.
What we seal
- Internal decorators’ caulk
- Cladding and panel joints

- Window and door perimeters
- Floor and skirting junctions
- Sanitary and kitchen joints
Construction mastic in Downend
Mastic follows everyone else, which means it absorbs every delay upstream. We agree a sequence at the start and adjust it as the site manager releases areas. That keeps the work right first time and saves rework. Site teams most often ask us about perimeter gaps outside the sealant’s range and mastic snags holding up handover, across window and door perimeters, internal decorators’ caulk and cladding and panel joints.

Construction in and around smaller places such as Downend is often barn conversions, small groups of houses or extensions to halls and schools. Perimeters, facade joints and internal sealant all need doing properly, however small the scheme.
Work we carry out comes with a 12-month guarantee. If an installation problem shows up, call 01277 525 020 or email drawings and photos and we’ll arrange a return visit.

What affects the price in Downend
A fixed quote reflects the actual work. It takes account of:
- Which sealant the job calls for
- Backing rod, priming and other preparation
- The total length or number of joints
- Distance, for remote addresses
The specified product makes a difference, and so does the preparation, from cutting out to priming and backing rod. Access, phasing and site requirements come into it too.
What we need to price the job
For an accurate fixed quote, we need a clear picture of the site. Send us:
- When you need the work done
- The type of building and who uses it
- The postcode of the building
- Anything awkward about access or site hours
The quickest route to a quote is a few photos and the site postcode. Upload them with the quote form, or call the office on 01277 525 020 or email us if you’d rather talk the job through.
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. Leave it late and they turn up on the snag list. Around Downend, it’s better to renew all the failing joints at once. Photos of every joint help us quote for the whole job.
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 you’ll have a fixed figure to work with.

Looking after the joints
Once the work is signed off, these steps help:
- Bring the mastic contractor in after the last trades are through
- Ask for joint and product checks before the package is urgent
- Keep finished joints away from paint, plaster and scrapers
- Brief the final clean team to avoid blades near sealant
If a joint is damaged after sealing, flag it early. Snags can be picked up in a planned close-out visit as agreed in the quote.
One unsealed frame can let water into finished internal areas. That usually means redoing finishes in a completed area, and a delay to handover. A check of every frame before decorators start is worth the time.
Surface by surface
Bathrooms, en suites and washrooms
Across a block of flats or a hotel, sanitary sealing is repeated in every room. A single team keeps the standard consistent, plot by plot or floor by floor.
Window and door perimeters
Inside, a paintable sealant or decorators’ caulk is used where the joint doesn’t move much. We follow what’s specified.

Downend is about 53 miles from central London. Construction around the commuter belt mixes station-side flats with refurbished offices and units, so mastic packages have to keep pace with busy programmes.
Recladding or extending a unit at a site like Red Shute Hill Industrial Estate (2.5 miles south-east of Downend) brings panel joints and frame perimeters into the programme. New wings at hospitals like West Berkshire Community Hospital, 4.7 miles to the south of Downend, bring long runs of window and panel joints to seal.
