About our construction mastic in Asheridge
On refurbishments, the mastic package typically includes cutting out old sealant as well as sealing new work. Existing joints have to be stripped back to sound faces, because fresh sealant can’t key into cured silicone, and on older buildings we ask for the asbestos survey before disturbing anything. After that, the joints are prepared and sealed to the specification. The enquiries we see most involve snag items on joints that need redoing before handover and new external sealant already peeling away, on internal decorators’ caulk, window and door perimeters and cladding and panel joints. For commercial sealant work in Asheridge, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.
Around smaller places like Asheridge, building work typically means conversions of farm buildings, a few new houses or an extension to a hall or school. Each still needs a proper mastic package: window perimeters, facade joints and internal sealant to the specification.
Every job we finish is backed by a 12-month workmanship guarantee. If our installation lets you down in that time, we return and fix it.

Leave it or put it right?
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. Around Asheridge, it’s better to renew all the failing joints at once, rather than one at a time. Photos of every joint help us quote for the whole job.
What a job costs comes down to how many linear metres there are, how much old material needs removing and the access. Call for a quote once you have the details.

Sites and facades in and around Asheridge
Asheridge is about 28 miles from central London. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, and main contractors there need mastic that keeps to the programme. Asheridge sits in one of the drier corners of the country, the South East. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, so the external programme keeps a little slack.
Projects at schools like Chartridge Combined School work to term dates, so mastic is programmed tightly. For contractors refurbishing units at places like Waterside Business Park, which lies south-east of Asheridge, the mastic covers cladding panels, roller-door and window perimeters.

What we are called out for in Asheridge
Swapping the specified sealant for a cheaper general-purpose product is a common cause of failure. A general-purpose silicone on a facade or a caulk in a wet area won’t perform like the specified product. We use what’s specified, and any substitute goes to you for acceptance.
If one of these sounds familiar, it’s time for a closer look:
- Frame gaps too wide for sealant alone
- Cracks opening in caulked internal joints
- Window and door perimeters that won’t pass inspection
- Early adhesion failures on new external joints
For contractors on a campus like Buckinghamshire New University, 3.5 miles south of Asheridge, facade and perimeter sealing has to fit around students and term dates.
Before you book anyone
- Is the sealant right for the movement and the substrate?
- Will failed sealant be removed rather than covered?
- Who will actually carry out the work
- Will RAMS and insurance details be available?
What the job involves on each surface
Internal decorators’ caulk
Caulk is easy to apply badly. A neat, consistent caulk line makes the decorators’ job quicker.
Fire-rated sealant where specified
Where the specification calls for fire-rated or intumescent sealant around service penetrations or linear gaps, we install it to the manufacturer’s tested detail. The design and sign-off of fire stopping sit with the designer, principal designer or fire engineer.
Cost factors for mastic packages
Quotes vary with the job. Expect it to depend on:
- Specialist products, such as fire-rated or hygienic sealants
- Joint width, depth and condition
- Distance, for remote addresses
- Access and working height
We don’t publish prices, because the scope varies so much from one building to the next. For a fixed figure, call for a quote.
Details that help us quote
Diagnosis starts before we arrive. Tell us:
- Whether the building will be occupied during the work
- Asbestos survey details if the building is older
- When you need the work done
- The product your specification calls for
Need a figure for a tender or a budget? We will quote against your scope and drawings you can plan around. If you have questions first, ring 01277 525 020 or email a schedule or drawings.
Doing it in-house
Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
