How we handle facade sealing in Little Heath
We are often asked to look at water coming in around frames. Failed perimeter sealant is a frequent cause. If the evidence points away from the sealant, we say so before quoting. If you are dealing with failed seals around shopfront and entrance frames and patch repairs that keep failing, we can put it right, on coping and flashing joints, stone and brick facade joints and window and door perimeters alike. Searching for sealant specialists in Little Heath? Mastic Doctor has worked for contractors, FMs and building owners since 2005, with CSCS-carded applicators.
Construction in a London area such as Little Heath 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.
Whoever the client is, the cover is the same: twelve months on the work we carried out. It doesn’t extend to damage, faults in the building or work by others, and we’re upfront about that.

How the job changes by surface
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.
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.

Looking after the joints
Once the work is signed off, a little attention goes a long way:
- Don’t wait for a second leak before calling
- Combine resealing with other works that need access
- Check that rainwater leaves the facade the way it was designed to
- Keep pressure washers away from fresh sealant
Keep gutters, sills and drainage paths clear. Good drainage keeps water moving off the facade.
Coordinate facade sealing with other external works. One set-up for several trades saves money and limits disruption.
What we can’t put right
Some faults sit outside our scope, and we point that out rather than sealing over them:
- Render or concrete edges that have broken away
- Arranging specialist high-level access, which is planned with the client
- Movement beyond what any sealant can handle
If in doubt, give us a call on 01277 525 020 or use the quote form and we’ll say what we think before you book.
Surfaces we seal

Related advice
Little Heath: questions and answers
Do you work in London buildings with loading restrictions?
Yes. Inductions, permits and timed loading are routine for us in London. Say when the building is occupied and when it’s quiet, and we will plan accordingly.
Can work at a site such as New City College fit around teaching?
Yes. Tell us the term dates, vacation periods and access windows, and we will plan the work around them. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.
Do you take on small jobs?
We quote for single jobs as well as large packages and programmes. Photos and a description are enough to start.
Do you use silicone for external joints?
Most facade and window perimeter joints take a low-modulus neutral-cure silicone. Hybrid or MS polymer, polyurethane and polysulphide sealants suit others, depending on the substrate and the specification.
How long do sealant joints last?
It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.
Can weather delay the job?
Outside, yes. Sealant needs a dry joint and a temperature within the product’s range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.
Do we need an asbestos check before resealing?
For older buildings, yes, check before work starts. The duty to manage asbestos sits with the dutyholder. If asbestos is suspected, work stops until it is tested.
Signs you need facade sealing in Little Heath
Not every failure is in the sealant: if the edge of the render, concrete or coating breaks away, the bead goes with it. We tell you when the edges need repairing before resealing.
If one of these sounds familiar, it’s time for a closer look:
- Water coming in around window frames
- Cladding panel joints that have opened up
- Failed seals around shopfront and entrance frames
- Unsightly perimeter sealant on a visible elevation
New wings at hospitals like King George Hospital, 0.6 miles to the west of Little Heath, bring long runs of window and panel joints to seal.
