Need facade sealing in Westcott?
Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.
Why deal with it now?
The longer a failed joint is left, the more the substrate suffers: wet edges break down, so repairs may be needed before resealing. Early action keeps it simple. Older rural buildings around Westcott move with the seasons, and rigid or tired sealant can’t keep up. A sealant with the right movement capability, correctly sized, lasts far better.
No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.
Why appoint us
- Fully insured, including public liability cover
- Standard and matched colours in many product ranges
- Clear, fixed quotes
- Colours chosen to suit frames, cladding or finishes where possible

How we handle facade sealing in Westcott
We are often asked to look at water coming in around frames. Very often the perimeter bead has cracked or lost its grip, though that isn’t the only cause. If the evidence points away from the sealant, we say so before quoting. Site teams most often ask us about damp patches beside frames after rain and weathered facade joints that have lost their grip, on cladding panel joints, coping and flashing joints and shopfront frames. One point of contact handles commercial sealant work in Westcott from the first photos to the final walk-round, for single jobs and planned programmes alike.
In the countryside around places like Westcott, conversion schemes put new frames into old stone, flint, brick or timber. A product that grips an irregular face, with a colour that suits the building’s character, is typically what’s needed.
Every job we finish is backed by a 12-month workmanship guarantee. If a joint we sealed fails because of how it was installed, we come back and put it right.

New build and refits around Westcott
Westcott lies roughly 44 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. The South East is one of the drier parts of the UK. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, so the external programme keeps a little slack.
New units and refits on sites such as Lawn Farm Business Centre (2.3 miles north-west of Westcott) need their panel and perimeter joints sealed to the specification. Hotel extensions and refits, at places such as The Five Arrows Hotel (1.3 miles east of Westcott), typically run between busy periods, so the sealing is squeezed into short windows.

What we are called out for in Westcott
Three-sided adhesion is a classic installation fault. Without rod or bond-breaker tape, the bead is held back and tears as the joint moves.
Any of the following is a good reason to get the joints checked over:
- Previous reseals run over old sealant
- Water coming in around window frames
- Weathered facade joints that have lost their grip
- Perimeter joints where frames meet the structure
New wings at hospitals like St John's Hospital, 4.6 miles south-east of Westcott, bring long runs of window and panel joints to seal.

Westcott: questions and answers
Can you take on a job at a hospital such as St John's Hospital?
Yes, hospitals are one of the sectors we cover. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Can you work at a site such as Lawn Farm Business Centre, by Westcott?
Yes, sites like Lawn Farm Business Centre are within our area, along with the rest of Westcott. Photos and a short description are enough for a first look.
Can you work in cold or wet weather?
Rain and frost can pause external sealing. The programme allows for it and we tell you if the forecast changes things.
Do you run new sealant over the existing bead?
No. Fresh silicone won’t grip cured silicone, so the existing bead is removed entirely and the faces are cleaned before resealing. That is what makes the new joint last.
How long do sealant joints last?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Sealant joints are maintenance items, so inspect them regularly.
What do you charge?
We don’t publish prices, as every site differs. With photos or drawings, we can give you a fixed quote.
Are you CHAS accredited?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member.
Aftercare for building managers
Cleaning and maintenance staff play a part too. Share these points with them:
- Note when each elevation was last resealed
- Keep sills, gutters and drainage paths clear
- Insist on a full cut-out when joints are renewed
- Avoid harsh cleaners on facade sealant
Anything drilled through a facade joint breaks the seal. Ask the installer to reseal it properly using a matching sealant.
In pre-2000 buildings, check the asbestos register before old sealant is cut out. Some older mastics contain it, and if it’s suspected, we stop until it has been tested.
Our process
We bring the products specified for the job, along with primers and backing rod. Joint faces are cleaned back to sound, dry surfaces, primer goes on where the manufacturer specifies it, and each bead is tooled to a neat concave finish. For a building around Westcott, tell us how to find it and who will meet us. Send that with the details and we’ll confirm the plan with the quote.
- We plan access and the order of elevations with the client.
- Weather and temperature are checked against the product’s limits.
- Each joint is cut out and the edges inspected.
- Joints are cleaned, primed if required and fitted with backing rod.
- Sealant is gunned in and tooled hard onto both faces.
- We hand over with our 12-month workmanship guarantee.
What we need from you
- Share the asbestos register for older buildings
- Move anything stored against the joints
- Let building users know which areas are affected
