Construction mastic in Kingswood
On refurbishments, the mastic package usually 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 the asbestos survey is checked first on older stock. After that, the joints are prepared and sealed to the specification. We work on internal decorators’ caulk, sanitary and kitchen joints and floor and skirting junctions, and the failures we’re asked to look at most are cracks opening in caulked internal joints and sanitary sealant damaged by following trades. Facilities teams, main contractors and managing agents in Kingswood tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.
On a small site around Kingswood, the mastic is best done in the fewest visits we can manage. Let us know the key stages and we will time the work so nothing waits on us.
Our workmanship is guaranteed for 12 months, in Kingswood as everywhere else we work. If our installation lets you down in that time, we return and fix it.

New build and refits around Kingswood
Kingswood 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 external mastic is timed for workable conditions and agreed with the site manager. Kingswood lies roughly 15 miles out from central London. Towns within reach of London tend to keep building, from flats to offices and schools, which keeps mastic packages in demand.
Hospital estates such as Headley Court (to the west of Kingswood) tend to grow and change in phases, often next to occupied wards, so facade and perimeter sealing has to fit the estates team’s plan. School extensions, at buildings such as Tadworth Primary School, typically run to the summer holidays, mastic included. Older buildings in the area around Kingswood, such as Fitznells Manor, 4.6 miles to the north of Kingswood, need care when sealed: the product has to suit soft or historic materials.
Kingswood is about 4 miles south-west of Coulsdon, in Surrey. If you are looking for construction mastic in Kingswood, we can help, as we do across Surrey. Across Surrey, 379 places are covered, including Kingswood. There’s a separate page for London, about 15 miles away.

What sets the cost
Before we quote, we look at:
- Any access equipment needed
- Backing rod, priming and other preparation
- Distance, for remote addresses
- Which sealant the job calls for
There’s no price list, because the scope varies so much from one building to the next. Call for a quote and we will price your job on its own details.
What to include in your enquiry
Diagnosis starts before we arrive. Let us know:
- Whether the building will be occupied during the work
- Whether an asbestos survey exists
- Clear photographs of the problem areas
- Anything awkward about access or site hours
Quotes are fixed against the scope you send, so you know the figure before anyone is on site. To ask for one, speak to us on 01277 525 020 or email drawings and photos.
Why act early in Kingswood
Some packages split mastic across the window fitter, kitchen fitter and plumber. The result tends to be uneven finishes and arguments about who should seal what. A single mastic package gives one point of responsibility. A failed joint lets water into a building whatever its size. Early resealing avoids the damage that follows a leak.
The product called for affects the cost, and so does the preparation, such as cutting out, priming or new backing rod. Access, phasing and site rules also count.
Why us?
- CHAS accredited
- Products installed to the manufacturer’s instructions

What the job involves on each surface
Kitchens and utility areas
Worktop upstands, sinks and splashbacks are sealed once the kitchen is fitted. A kitchen-suitable sealant is used and hygienic or food-safe grades wherever food contact is possible.
Snagging before handover
Snagging is often the final mastic stage. Snags are cleared room by room and damaged joints are redone rather than patched.
Keeping the joints sound
To get the most from the new sealant:
- Brief the final clean team to avoid blades near sealant
- Allow flexibility for external sealing in damp or cold weather
- Check frame gaps are within the sealant’s range before sealing
- Protect sealed areas from following trades
If a joint is damaged after sealing, flag it early. Snags can be picked up in a planned close-out visit.
Frames with gaps too wide for sealant need sorting before the mastic goes on. Sealant stretched over an oversized gap won’t last. We raise them during our first walk of the area.
Common questions from Kingswood clients
Will you plan work around the academic year at somewhere like University for the Creative Arts - Epsom?
Yes, holiday working periods are the norm on campus jobs. Let us know which documents your site asks for, and we’ll confirm them alongside the quote.
Is Kingswood too far out for you?
No. Places such as Kingswood are covered as much as the big towns. Our area covers London and the South East counties. Where we can, we group nearby jobs to make the most of each trip.
Do your applicators hold CSCS cards?
Our applicators are CSCS-carded, and we hold CHAS accreditation and Constructionline membership. We confirm any paperwork you need with the quote.
Can fire-rated sealing at service penetrations be included?
We install fire-rated sealant where it is the specified product, working to the specification and the manufacturer’s installation guidance. If the detail calls for collars, wraps or batts instead, we’ll tell you.
How long do sealant joints last?
There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular inspection is the best way to catch problems early.
How soon can the area be used again?
The product and site conditions decide that. Some take light use quickly, others need longer to cure, and we confirm it before leaving site.
When can you be on site?
We are in the office from 8am until 5pm, Monday to Friday. Let us know your site hours and access windows, and the work will be planned around them.
