What the job involves on each surface
Kitchens and utility areas
Commercial kitchens often need hygienic or food-safe sealants. We follow the specification and seal to a smooth, cleanable finish.
Internal decorators’ caulk
Where the specification calls for it, acrylic decorators’ caulk goes on non-moving internal gaps before painting. It’s for gaps that stay still and get painted, and we use a flexible sealant where there’s movement.
Construction mastic in Westwood, done properly
We work to the specification and the programme rather than whatever product is to hand. Where the specification names a product, we use it. Joint widths, backing, primers and tooling follow the manufacturer’s guidance so the detail on the drawing is what ends up on site. The enquiries we see most involve cracks opening in caulked internal joints and sanitary sealant damaged by following trades, on floor and skirting junctions, window and door perimeters and sanitary and kitchen joints. Searching for sealant specialists in Westwood? Mastic Doctor has worked for contractors, FMs and building owners since 2005, CHAS accredited and a Constructionline member.
Construction in and around smaller places such as Westwood is often barn conversions, small groups of houses or extensions to halls and schools. Each still needs a proper mastic package: window perimeters, facade joints and internal sealant to the specification.
Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and we explain exactly what that covers when we quote.

What else we do in Westwood
What sealant work can’t fix
We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:
- Defective windows, doors or glazing units (the supplier or installer’s job)
- Damage to finishes by other trades after we have sealed
- Oversized gaps that need packing or adjustment by others
Not sure which it is? You can call 01277 525 020 or email us and we will tell you honestly.
Where we work in Westwood

Sites and facades in and around Westwood
Westwood sits in one of the drier corners of the country, the South East. Winter mornings still bring frost and condensation on frames and panels, so external mastic is timed for workable conditions and agreed with the site manager. Westwood lies roughly 18 miles out from central London. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, which keeps mastic packages in demand.
Historic houses such as Cobham College, 4.6 miles to the east of Westwood, are a reminder of the older buildings in the wider area, where sealing against old stone, brick or timber needs compatible products. University estates such as University of Greenwich, 2.4 miles north-west of Westwood, tend to have a rolling programme of new buildings and refurbishments, each with window perimeters and facade joints to seal.
Westwood is about 3 miles south of Swanscombe, in Kent. If you are looking for construction mastic in Westwood, we can help. 931 places across Kent fall within our area, Westwood among them. Sites around London have their own page, about 18 miles away.

Common questions from Westwood clients
Is Westwood too far out for you?
Not at all: smaller places are covered as well as towns. We cover Greater London and the counties of the South East. Good photographs up front let us bring everything on the first visit.
Could you schedule work at a campus like University of Greenwich for the vacation?
Yes. Education sites normally want the work in vacations or in phases during term, and we plan to suit. Let us know which documents your site asks for, and we’ll confirm them alongside 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. Fire-stopping design and sign-off sit with the designer and building control.
Do you guarantee new-build sealant work?
It carries a 12-month guarantee on our workmanship. We carry five million pounds of public liability insurance.
Does weather matter for sealant work?
For external joints, 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.
When is resealing likely to be due?
Nobody can honestly give a figure in years, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.
What hours do you work?
The office is staffed Monday to Friday, from 8am until 5pm. Tell us your site hours and access windows and the work will be fitted around them.
Site staff or a sealant specialist?
Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we will confirm the paperwork you need with the quote.
Redoing a failed joint typically costs more than getting it right at the outset, 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.

When to call us in Westwood
A new building moves while it dries and settles. 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.
What tends to prompt an enquiry:
- Old sealant on a refurbishment that needs stripping before new work
- Different trades sealing to different standards
- Mastic snags holding up handover
- Cracks opening in caulked internal joints
For contractors at a school such as Bean Primary School, sealing has to be finished before term starts.
What your quote should include
- Their pre-qualification and accreditations
- Can the work be phased to keep areas open?
- Whether primer will be used where the manufacturer specifies it
- Whether their applicators hold CSCS cards
