Construction mastic in Leatherhead, done properly
On refurbishments, the mastic package normally 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. New and existing joints then get the same preparation. We work on floor and skirting junctions, brick and block movement joints and cladding and panel joints, and what we are called in for most is sanitary sealant damaged by following trades and existing joints on a refurb that need cutting out and resealing. For commercial sealant work in Leatherhead, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.
In towns like Leatherhead, sites are normally modest: small housing schemes, extensions to schools and surgeries, refurbished shops and offices. A mastic package on a smaller site still needs the same care at window perimeters and facade joints.
The 12-month guarantee is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we spell out the cover before we begin.

We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To start the process, call 01277 525 020 or email the details over.
Facades, frames and programmes in Leatherhead
Leatherhead is in the South East, one of the UK’s drier regions. 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. Leatherhead is about 17 miles from central London. Construction around the commuter belt mixes station-side flats with refurbished offices and units, and main contractors there need mastic that keeps to the programme.
For contractors on a campus like University for the Creative Arts, 3.5 miles to the north-east of Leatherhead, facade and perimeter sealing has to fit around students and term dates. When a school such as Leatherhead Trinity School and Children's Centre is extended or refurbished, the mastic package is often squeezed into the holidays.
Leatherhead is about 4 miles south-west of Epsom, in Surrey. If you are looking for construction mastic in Leatherhead, we can help. Leatherhead is one of 379 places in Surrey on our list for mastic packages. We also cover London, around 17 miles from Leatherhead.

Why it’s worth doing now in Leatherhead
Getting the mastic contractor involved early pays off. Early involvement means gaps, products and access are sorted before the programme bites rather than at the snagging stage. Called in at the end, the same issues surface during handover. Many buildings in towns like Leatherhead have been extended or altered, so joints between old and new are often the first to go. Resealing them early protects the building behind.
We don’t publish prices, since every building and every scope is different. Call for a quote.

Different surfaces, different methods
External facade and movement joints
Movement joints in the facade are sealed with a product suited to the expected movement. We set the depth with backing rod to avoid three-sided adhesion.
Snagging before handover
Damaged, missed or untidy joints make up most snag lists. We price snagging as part of the package or as a separate visit.
Common problems we fix in Leatherhead
Shrinkage and settlement in the first months put new joints under strain. Plaster, screeds, timber and blockwork all shrink as they lose moisture, which opens up internal joints, particularly where caulk has been used in a joint that moves. Picking a flexible sealant where there’s movement keeps snags down.
Any of the following is a good reason to get the joints checked over:
- New external sealant already peeling away
- Failed sealant in an existing building being refurbished
- A long mastic snag list close to completion
- Frame gaps too wide for sealant alone
For contractors refurbishing units at places like Leatherhead Industrial Estate (under half a mile west of Leatherhead), the mastic covers cladding panels, roller-door and window perimeters.

Your questions answered
Can you take on a job at a hospital such as Leatherhead Community Hospital?
Yes, healthcare and care buildings are part of our work. We follow the site’s permits, sign-in and infection-control procedures in every area.
Can work at a site such as University for the Creative Arts fit around teaching?
Yes. Education sites normally want the work in vacations or in phases during term, and we plan to suit. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.
Can you work while the building is occupied?
Typically, yes. We phase the work so most of the building stays in use, with each area protected and signed.

How do I request a quote?
You can use the quote form on this site; alternatively, phone 01277 525 020 or email us. Photos, drawings or a joint schedule help us quote quickly.
Can fire-rated sealing at service penetrations be included?
Fire-rated sealant can be included where it’s specified, installed to the product’s tested detail. Fire-stopping design and sign-off sit with the designer and building control.
When is resealing likely to be due?
It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.
