Facade sealing in Redhill, done properly
External joints face UV, rain, temperature swings and building movement all year, so they don’t last indefinitely. Life depends on movement, weathering, product choice and the quality of the original work. When the time comes, we cut the old sealant out completely and start again. We work on perimeter joints where frames meet the structure, stone and brick facade joints and shopfront frames, and the failures we’re asked to look at most are hard, chalky sealant that no longer flexes and staining on stone next to old sealant. Searching for sealant specialists in Redhill? Mastic Doctor has worked for contractors, FMs and building owners since 2005, with CSCS-carded applicators.
For contractors on site in a town like Redhill, the mastic has to fit the programme: perimeters sealed before scaffold is struck, internal sealant after decoration, snags before handover. Send drawings and the programme and we’ll price to suit.
We stand behind the joints we seal: 12 months, guaranteed. It covers how we prepared and applied the sealant.

New build and refits around Redhill
The South East is one of the drier parts of the UK. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, so external mastic is timed for workable conditions and agreed with the site manager. Central London is about 18 miles from Redhill. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, and main contractors there need mastic that keeps to the programme.
New wings at hospitals like East Surrey Hospital, 1.3 miles south of Redhill, bring long runs of window and panel joints to seal. Units on estates such as Kingsfield Business Centre (to the south-east of Redhill) tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal. Projects at schools like St Joseph's Catholic Primary School work to term dates, so mastic is programmed tightly.

Looking after the joints
Sealant joints are maintenance items, and their life depends on movement, exposure, cleaning and use. Our advice:
- Avoid patch repairs on failed facade joints
- Ask about asbestos in pre-2000 mastic
- Add perimeter sealant to planned maintenance checks
- Keep sills, gutters and drainage paths clear
Keep gutters, sills and drainage paths clear. Sealant copes better when water runs off the facade as designed.
Deal with sections that fail early as soon as they show. Small repairs stop small leaks becoming large ones inside the building.

Work for main contractors and building owners
We take on planned maintenance as well as one-off repairs: working through a building or an estate in stages that fit your budget. Redhill can form part of a wider programme.
If you look after buildings for someone else, you need clear quotes and clear reporting. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative.
Should maintenance staff do it?
There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and we will confirm the paperwork you need with the quote.
Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong typically costs more in the end than doing them right.
Common questions from Redhill clients
Is Kingsfield Business Centre, near Redhill, within your area?
Yes, sites like Kingsfield Business Centre are within our area, along with the rest of Redhill. A few photos and the unit address let us price the work.
Could you schedule work at a campus like Reigate College for the vacation?
Yes. Tell us the term dates, vacation periods and access windows, and we’ll plan the work around them. We’re CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.
Which sealant will you use?
Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
Is it fine to apply new sealant on top of old?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, since fresh sealant will not bond reliably to aged material.
What’s the quickest route to a quote?
The quote form is the simplest route, though you can also speak to us on 01277 525 020 or use the quote form. Photos, drawings or a joint schedule help us quote quickly.
Do you take on small jobs?
Whatever the size, the process is the same: details, then a fixed price, then sealing, then a 12-month guarantee.
Do you replace windows or glass?
No. A glazing contractor handles that. We reseal window perimeters, panel joints and frame-to-structure perimeters.
When something else is needed
Part of a good diagnosis is knowing where sealant stops. We’ll tell you if the real problem is one of these:
- Providing access systems for the work
- Cracked or spalling substrates that need repair before sealing
- Water getting in through cracked render or porous masonry
Not sure which it is? You can speak to us on 01277 525 020 or send photos by email and we will tell you honestly.

From enquiry to sign-off
When we get to site, we report to your site contact and complete whatever induction the building runs. Everything around the joints gets protected before anything is cut or cleaned, and the work normally takes a day or two for a few elevations, and longer where access has to be moved around the building. Most work in Redhill is one building at a time: a school, a unit, an office or a block. We start with your photos, drawings or a site visit, then send a fixed quote.
- Photos, drawings or a visit tell us about the joints and the access.
- We confirm the joint type, movement and the specified product.
- The existing bead comes out in full and the joint faces cleaned.
- Primer goes on where the product data asks for it.
- Backing rod is fitted and the new sealant gunned in and tooled.
- We go over the completed work with you before leaving.
Preparing the site
- Tell staff and tenants when we’ll be in
- Point out parking and an unloading spot
- Point out any areas we must not close
Quotes
Send us photos, drawings or a joint schedule are often enough for a fixed quote. Where a site visit makes more sense, we’ll arrange one.
Advice
Different surfaces, different methods
Brick and stone facades
Stone can absorb plasticisers from the wrong sealant. We use a product suitable for the stone where the specification names one.
Window and door perimeters
Frame-to-wall joints at windows and doors are the facade joints we reseal most. A low-modulus, neutral-cure product suits most frame-to-wall joints, tooled to shed water.
