Facade sealing in Withdean
Most facade joint failures trace back to the joint, not just the sealant. The width has to suit the expected movement and the sealant’s movement capability, and closed-cell rod sets the depth, keeping the bond to two faces, often at around 2:1 width to depth, as the manufacturer advises. The enquiries we see most involve draughts around frames and panels and unsightly perimeter sealant on a visible elevation, on stone and brick facade joints, window and door perimeters and cladding panel joints. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Withdean it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Conversions around smaller places like Withdean often join new frames to old masonry or timber, which leaves joints between old walls and new frames that need a sealant able to take the movement.
What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Withdean: questions and answers
Is a smaller place like Withdean outside your area?
Not at all. Withdean is within our area. London and every South East county are within our area. Good photographs up front let us bring everything on the first visit.
Do you cover business parks and estates near Withdean, such as Goldstone Retail Park?
Yes. Our area takes in Withdean and its surroundings, with estates and business parks such as Goldstone Retail Park included. To start, just call the office on 01277 525 020 or email the details over with the unit, the joints involved and your access times.
Is it okay to overlay old mastic?
No. A bead run over old sealant soon lifts. We remove the failed sealant, clean the faces, set the depth and reseal.
Is old mastic on our building likely to contain asbestos?
Some older mastics, especially in pre-2000 buildings, can contain asbestos. The dutyholder’s asbestos register should be checked first. Removal of asbestos isn’t something we do.
Does the weather affect the work?
It can, when the joints are outside. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.
How long will the new sealant last?
There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.
Do you take on small jobs?
Small jobs are welcome alongside larger packages. Photos and a description are enough to start.

What else we do in Withdean
New build and refits around Withdean
Withdean is within about 2 miles of the coast. Facades and window perimeters on coastal schemes take more wind-driven rain, and salt air nearer the shore, and the sealant, primer and backing need choosing with that in mind. A 2-mile radius around Withdean takes in plenty of hotels. Hotel schemes tend to have fixed reopening dates, so the mastic is programmed tightly with the other trades.
When a college such as Varndean College, under half a mile to the east of Withdean, builds or refurbishes, the mastic package normally has to fit around students and staff. University estates such as University of Brighton Moulesecoomb Campus, 1.5 miles to the east of Withdean, tend to have a rolling programme of new buildings and refurbishments, each with window perimeters and facade joints to seal.

Looking after the joints
Every sealant joint needs some looking after, and their life depends on movement, exposure, cleaning and use. We suggest:
- Record the product and colour used on each elevation
- Clear debris that holds water against joints
- Check the asbestos register before old mastic is disturbed
- Keep pressure washers away from fresh sealant
Blocked sills and gutters push water at the joints. Good drainage keeps water moving off the facade rather than sitting against the joints.
Coordinate facade sealing with other external works. Sharing the access keeps the cost down and cuts time on site.
How the job changes by surface
Brick and stone facades
Joints in natural stone need care to avoid staining. The specified stone-compatible sealant is what we use, with masked edges for a clean line.
Precast concrete panels
Precast panel joints have to absorb thermal and structural movement. A sealant of the right movement class goes in over backing rod, primed where the maker specifies.
What we can’t put right
Not every problem is a sealant problem, and we are upfront when that’s the case. It won’t fix:
- Damp caused by condensation inside the building
- Movement beyond what any sealant can handle
- Render or concrete edges that have broken away
If in doubt, speak to us on 01277 525 020 or use the quote form and we will say what we think before you book.
What we seal
- Coping and flashing joints
- Cladding panel joints
- Perimeter joints where frames meet the structure
- Stone and brick facade joints
- Window and door perimeters

Signs you need facade sealing in Withdean
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.
What tends to prompt an enquiry:
- New sealant peeling off old mastic
- Damp patches beside frames after rain
- Draughts around frames and panels
- Gaps between rainscreen or cladding panels
Units on estates such as Goldstone Retail Park (1.3 miles south-west of Withdean) tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal.
What your quote should include
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
- Their plan for phasing and protecting the area
- Are they CHAS accredited or on Constructionline?
- The named product and why it was chosen
