Construction mastic in Ashley Green, done properly
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 Ashley Green, send drawings and the specification through our quote form. We work on brick and block movement joints, window and door perimeters and sanitary and kitchen joints, and what we’re called in for most is caulk cracking where joints are moving more than expected and failed sealant in an existing building being refurbished. For commercial sealant work in Ashley Green, you deal with one contact from quote to sign-off, whether it’s one building or several.
In the countryside around places like Ashley Green, conversion schemes put new frames into old stone, flint, brick or timber. Those joints need a sealant that suits an uneven, sometimes porous surface, and often a colour chosen for the building.
What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Aftercare for building managers
Sealant joints are maintenance items, and how long they last depends on how they’re treated. Our advice:
- Keep product details for future maintenance
- Keep scrapers and abrasive pads off new beads
- Ask installers to correct oversized gaps first
- Ask for joint and product checks before the package is urgent
Any damage after we’ve finished should go on the snag list right away. We can return to clear snags before handover, priced as part of the package or separately.
One unsealed frame can let water into finished internal areas. That usually means redoing finishes in a completed area and possibly a delayed handover. A check of every frame before decorators start is worth the time.
Work for main contractors and building owners
Facilities managers want contractors who arrive with the paperwork sorted. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we will confirm with the quote.
For main contractors, we work as the sealant subcontractor on new-build and refurbishment projects. We work to your programme, your specification and your site rules, and our applicators hold CSCS cards.
When to call us in Ashley Green
Dust is the enemy of adhesion on a construction site. Dust, film adhesive, damp and grease on the joint faces prevent a proper bond so faces get cleaned, and primer goes on wherever the maker specifies, even on new work.
It’s worth sending us details if you spot any of the following:
- A mastic package split between trades with no clear owner
- A long mastic snag list close to completion
- Cracks opening in caulked internal joints
- Failed sealant in an existing building being refurbished
For a contractor working at a hospital such as Hemel Hempstead Hospital, 5 miles east of Ashley Green, perimeter and facade sealing is planned around patients and deliveries.
Questions to ask before you book
- How joint depth will be controlled
- Whether old or failed sealant will be cut out, not overlaid
- Do they follow the manufacturer’s priming guidance?
- The named product and why it was chosen
Why it’s worth doing now in Ashley Green
Refurbishments sometimes budget for new windows when the frames are sound and only the seal has failed. If the frame is in good order, cutting out and resealing the perimeter can be all it needs and that’s a far smaller job. We will say so if a frame itself is the problem. Halls, stores and units around places like Ashley Green may not be checked every day, so a failed joint can leak for a while before anyone sees it. Renewing joints in good time avoids the problem.
No two sites price the same: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.

Central London is about 27 miles from Ashley Green. Towns within reach of London tend to keep building, from flats to offices and schools, and each scheme needs its mastic sealed to programme. The South East is one of the drier parts of the UK. Winter mornings still bring frost and condensation on frames and panels, which is why external dates are agreed with the site manager.

Questions about Ashley Green
Does your area include sites such as River Park Industrial Estate, near Ashley Green?
Yes, sites like River Park Industrial Estate are within our area, along with the rest of Ashley Green. Send details of the unit and the work through our quote form for a quick quote.
Can you work around term dates at a campus such as Buckinghamshire New University?
Yes, holiday working periods are the norm on campus jobs. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.
Do you take on mastic snagging only?
Yes, we can. Send the snag list or photographs and we will price it, then clear it to your programme.
How long before the joints can be used?
We will confirm how long the chosen product needs to cure, and sign any area that should be left alone.
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.
What will the job cost?
Each job is quoted on its own details. To get one, speak to us on 01277 525 020 or email a schedule or drawings with a description of the work.
Does weather matter for sealant work?
Outside, yes. The joint has to be dry and within the product’s temperature range, so damp, frosty or very cold days can stop external work. Internal work is rarely affected.
