About our construction mastic in Westcott
External mastic depends on the weather in a way most internal trades don’t. Cold or damp mornings, frost and condensation on frames can all hold external sealing up so it helps to sequence elevations with some flexibility. Internal areas can normally carry on while the outside waits. Most enquiries involve different trades sealing to different standards and mastic snags holding up handover, across internal decorators’ caulk, brick and block movement joints and cladding and panel joints. A specialist sealant contractor works differently from a general builder: in Westcott, that means joint design, primers and backing rod as standard.
For a site near Westcott, the mastic visit is planned so the right sealants, primers and backing rod are on hand. Send drawings or photos and the programme and we’ll quote to suit.
We sign every job off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.

Construction mastic in Westcott: the local picture
At about 22 miles from central London, Westcott is within reach of the capital. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, and main contractors there need mastic that keeps to the programme. There are a number of hotels within about 2 miles of Westcott. Hotel refurbishments often run to tight programmes between busy periods, and perimeter and sanitary sealant has to keep up.
Older buildings in the area around Westcott, such as Polesden Lacey, 2.2 miles to the north of Westcott, need care when sealed: the product has to suit soft or historic materials. When units on a site such as Chapel Lane Industrial Estate, under half a mile to the north of Westcott, are refurbished or reclad, the panel joints and window perimeters are part of the mastic package.
Westcott is about 2 miles west of Dorking, in Surrey. If you’re looking for construction mastic in Westcott, we can help, as we do across Surrey. Our Surrey coverage takes in 379 places, from busy centres to rural villages. For work in that direction, see our London page.

What’s near Westcott
Locally, jobs take us to sites close to The Priory CofE Voluntary Aided School, Milton Heath and The Nower and Pippbrook House and the streets around them.

How the quote is worked out
Quotes vary with the job. Expect it to depend on:
- The site’s rules and procedures
- Which sealant the job calls for
- Access and working height
- Phasing around occupants
Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.
What we need to price the job
Whether it’s one area or a whole building, these details speed things up:
- Whether an asbestos survey exists
- Clear photographs of the problem areas
- What the building is and how it’s used
- Access details, including height
If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price against exactly what is specified. Smaller jobs need nothing more than photographs and a few notes.
When something else is needed
Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. It won’t fix:
- Joint design decisions that belong to the architect or engineer
- Frame gaps too wide for sealant, which the installer needs to correct
- Deciding which fire-stopping product a penetration needs
If you are not sure, just call 01277 525 020 or send details through our quote form and we will give you a straight answer.
What we seal
- Floor and skirting junctions
- Cladding and panel joints
- Internal decorators’ caulk
- Sanitary and kitchen joints
- Window and door perimeters
- Brick and block movement joints
How the job changes by surface
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.
Window and door perimeters
Perimeter joints between frames and the structure are the weather line on any new building. We use the specified perimeter sealant, usually a low-modulus neutral-cure silicone and set the depth with backing where needed.
Your questions answered
Can you take on a job at a hospital such as Dorking Community Hospital?
Yes. We work in healthcare settings as well as offices and schools. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Is Westcott off your patch?
No. Small places get the same service as large ones. We cover Greater London and the counties of the South East. Where we can, we group nearby jobs to make the most of each trip.
Do you take on mastic snagging only?
Yes. Send the snag list or photos and we will price it, then clear it to your programme.
Is the mastic package guaranteed?
Each package is backed by a 12-month guarantee. We carry five million pounds of public liability insurance.
Do you offer coloured sealant?
That depends on the product specified. Some ranges offer many colours, others very few, so the available colours are confirmed with the quote.
Can fire-rated sealing at service penetrations be included?
Where the specification calls for fire-rated or intumescent sealant around service penetrations or linear gaps, we install it to the manufacturer’s tested details. The design and sign-off belong to the designer, fire engineer or building control.
Will you quote for a small job?
Whatever the size, the process is the same: details, then a fixed price, then sealing, then a 12-month guarantee.
Why it’s worth doing now in Westcott
When a package runs over budget, downgrading the product is a common first thought. A failed joint in the defects period costs far more than the product difference, especially externally. Where an alternative is genuinely suitable, we’ll say so. One visit to deal with every failing joint makes more sense than several trips to a place like Westcott. Photos of every joint help us quote for the whole job.
The price depends on how many linear metres there are, what has to come out first and the access. Call for a fixed quote once you have the details.

Common problems we fix in Westcott
Shrinkage and settlement in the first months put new joints under strain. Plaster, screeds, timber and blockwork all shrink as they lose moisture and internal caulk in a moving joint is normally the first to crack. Picking a flexible sealant where there’s movement keeps snags down.
What tends to prompt an enquiry:
- Existing joints on a refurb that need cutting out and resealing
- Frame perimeters left unsealed or poorly sealed
- Oversized or tapered gaps around new frames
- Inconsistent sealant finishes from plot to plot
For a contractor at a hotel such as The Bell Hotel, which lies east of Westcott, the mastic often has to be finished before a reopening date.
Questions to ask before you book
- How the joint faces will be prepared and primed
- The terms of the workmanship guarantee
- How they’ll work around occupants
- Their pre-qualification and accreditations
