How we handle facade sealing in Forestdale
Access is part of every facade job, and we plan it with you before quoting. Let us know what access exists or is planned, and any site rules we need to work around, so the price covers the real job. If you’re dealing with sealant pulling away from frames or panels and perimeter joints where frames meet the structure, we can put it right. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Forestdale it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Construction in a London area such as Forestdale means working on constrained sites: limited storage, booked deliveries and access shared with other trades. Mastic is usually one of the last trades on each elevation or floor, so we keep to the programme and the order of trades the site sets.
Every job we finish is backed by a 12-month workmanship guarantee, in Forestdale as everywhere else we work. If a joint we sealed fails because of how it was installed, we come back and put it right.

What the job involves on each surface
Render and coated surfaces
Rendered and painted facades need a sound edge for the sealant to bond to. Loose coatings are cleaned back first.
Window and door perimeters
Frames grow and shrink with temperature, and the perimeter joint has to follow. Rod placed at the right depth lets the bead stretch.
Site staff or a sealant specialist?
Redoing a failed joint normally costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.
For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.
When something else is needed
Before quoting, we check that sealant is the right answer. It won’t put right:
- Movement beyond what any sealant can handle
- Leaks from roofs, gutters or failed flashings rather than sealant joints
- Render or concrete edges that have broken away
If in doubt, ring 01277 525 020 or send photos by email and we will say what we think.

Sites and facades in and around Forestdale
Site traffic in Forestdale falls within London’s ULEZ, like everywhere else in Greater London. Deliveries are booked and storage is tight, so mastic materials come in as needed. There are several hotels within about 2 miles of Forestdale. Hotel extensions and refits normally have to fit around bookings, so mastic dates are tight.
Projects at schools like Courtwood Primary School work to term dates, so mastic is programmed tightly. For contractors refurbishing units at places like Vulcan Way Industrial Estate (1.5 miles east of Forestdale), the mastic covers cladding panels, roller-door and window perimeters. For a contractor working at a hospital such as Bethlem Royal Hospital, 2.6 miles north of Forestdale, perimeter and facade sealing is planned around patients and deliveries.

Questions we are asked in Forestdale
Can you take on a job at a hospital such as Bethlem Royal Hospital?
Yes, healthcare and care buildings are part of our work. Each area is agreed with the ward or department and the estates team in advance.
Can you cope with the access rules in a London building?
Yes, most London buildings have access rules of some kind, and we plan around them. Say when the building is occupied and when it’s quiet, and we will plan accordingly. The ULEZ covers the whole of Greater London, which we allow for
Should we check old sealant for asbestos?
It’s worth checking in any building from before 2000. The dutyholder holds the asbestos register. If asbestos is suspected, work stops until it is tested.
Do you hold CHAS accreditation?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member.
Do you seal on top of existing sealant?
No, never. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.
Can you find out why a window is leaking?
Yes. We check the sealant joints and report what we find before quoting. If the water seems to come from a roof, sill or the glazing unit instead, we say so.
Do you take on small jobs?
Small jobs are welcome alongside larger packages. Send details for a fixed quote.
Diagnose, treat, sign off
Site rules come first: sign-in, induction and whatever permit system the building uses. Once we are cleared to begin, the joints are worked through in the order agreed with your site contact.

- We confirm the joint type, movement and the specified product.
- The existing bead comes out in full.
- Primer is applied where the maker specifies it.
