Facade sealing in West Dean, done properly
Weather decides a lot in facade sealing. Joints have to be dry and the air and surface temperature within the product’s range, so frosty or damp mornings can hold work back. We build that into the programme and tell you if the forecast changes the plan. We work on shopfront frames, stone and brick facade joints and perimeter joints where frames meet the structure, and the failures we’re asked to look at most are cladding panel joints that have opened up and failed seals around shopfront and entrance frames. Whether you call it commercial sealant work, mastic application or joint sealing, the work in West Dean is the same: the right product in a properly prepared joint.
Sites around smaller places like West Dean can be a fair drive from suppliers, so we come with everything the package needs. Drawings, photographs and the programme let us give a fixed quote.
We stand behind the joints we seal with a 12-month guarantee. It covers how we prepared and applied the sealant, and if something we did falls short, we return to it.

Common questions from West Dean clients
Is West Dean too small for you to travel to?
No. Places such as West Dean are covered as much as the big towns. We cover Greater London and the counties of the South East. Good photographs up front let us bring everything on the first visit.
Is a hospital such as Chichester Centre somewhere you can work?
Yes, hospitals are one of the sectors we cover. We follow the site’s permits, sign-in and infection-control procedures in every area.
What’s the quickest route to a quote?
There are four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. The first step only needs photographs and a postcode.
Is any job too small?
Single areas, one-off repairs and whole buildings are all quoted the same way: details, then a fixed price, then sealing, then a 12-month guarantee.
Do you work to architects’ specifications?
Yes. The specification and the manufacturer’s installation guidance are what we work to, and we raise anything unclear before work begins.
Do you take on multi-site work?
Yes. Several buildings can share a single quote, and you deal with one contact throughout.
Can the sealant be colour-matched?
That depends on the product. Some ranges offer many colours, others very few, so the available colours are confirmed with the quote.
What happens if it’s left?
Failed joints let in more than water: occupants notice draughts and cold spots around windows. A new seal closes the gap for both. Older rural buildings around West Dean 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.
We don’t publish prices, because the scope varies so much from one building to the next. For a fixed figure, call for a quote and we will price your job on its own details.

Honest limits
Honesty saves time and money. New sealant won’t cure:
- Damp caused by condensation inside the building
- Joints too narrow for the movement they take, which need redesign
- Work on the window or framing system itself
If you are not sure, just call 01277 525 020 or email drawings and photos and we’ll give you a straight answer.
Joints and surfaces we work on
- Shopfront frames
- Stone and brick facade joints
- Perimeter joints where frames meet the structure
- Coping and flashing joints
- Window and door perimeters
- Cladding panel joints
Different surfaces, different methods
Cladding panel joints
Joints between cladding panels open and close with temperature. The sealant has to match the movement and the panel finish, as the specification sets out.
Precast concrete panels
Precast arrises sometimes crumble or carry old residue. Faces are cleaned to sound concrete, and damaged edges are reported before sealing.

Keeping the joints sound
Every sealant joint needs some looking after, and how long they last depends on how they’re treated. Our advice:
- Combine resealing with other works that need access
- Add perimeter sealant to planned maintenance checks
- Insist on a full cut-out when joints are renewed
- Ask about asbestos in pre-2000 mastic
Hold back any cleaning crew until the joints have had their stated cure time. Pressure washers and harsh cleaners can damage a fresh bead, so brief your window cleaners.
Building facade joints into a maintenance cycle avoids emergency repairs. Regular checks let you renew joints before water gets in, rather than waiting for a ceiling stain.
Building owners, agents and FMs in West Dean
We take on planned maintenance as well as one-off repairs: resealing failed joints building by building, on a schedule that suits your budget. Sites in West Dean can sit alongside others in a wider programme.
Hospitality, education, healthcare, office and retail clients come to us directly as well. We plan around the way the building is used, so the building keeps working while we do.
From enquiry to sign-off
When we get to site, we report to your site contact and complete whatever induction the building runs. Floors, finishes and fittings next to the joints are covered before any cutting starts, with the work itself typically taking a day or two for a few elevations, and longer where access has to be moved around the building. If others near West Dean need work, visits can be combined. A fixed quote is given before anything starts.
- First we review photos, drawings or what we saw on a visit, and agree how each joint will be reached.
- The old bead is cut away completely, not overlaid.
- Joint faces are cleaned to firm, sound material, with primer where the sealant maker specifies it.
- Backing rod, or bond-breaker tape in shallow joints, limits the depth.
- The new sealant goes in and is tooled firmly onto both faces.
- The completed runs are checked with you, then the 12-month guarantee applies.
Getting the site ready
- Agree which areas must stay open
- Let building users know which areas are affected
- Send asbestos survey details if the building is pre-2000
Request a quote
Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price against exactly what is specified. For smaller jobs, photographs and a description will do.
Advice
New build and refits around West Dean
Central London is about 51 miles from West Dean. Construction around the commuter belt mixes station-side flats with refurbished offices and units, which keeps mastic packages in demand. Rainfall across the South East, West Dean included, is lower than in many parts of the UK. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, so we time external mastic for dry faces and agree it with the site team.
For contractors at a school such as West Dean CofE Primary School, sealing has to be finished before term starts. Historic houses such as West Dean House, 0.1 miles north-east of West Dean, are a reminder of the older buildings in the wider area, where sealing against old stone, brick or timber needs compatible products. Projects at colleges like West Dean College of Arts and Conservation (to the north-east of West Dean) tend to run to term dates, so the mastic is planned tightly.
