About our facade sealing in Clay Hill
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, and we will fit the work around it. If you are dealing with leaks at window and door perimeters and failed seals around shopfront and entrance frames, we can put it right, on perimeter joints where frames meet the structure, window and door perimeters and cladding panel joints alike. One point of contact handles commercial sealant work in Clay Hill from the first photos to the final walk-round, whether it’s one building or several.
Around Clay Hill, as across London, much of the work is refurbishing existing buildings as well as building new ones. New frames, overcladding and fit-outs all end in perimeter and facade joints, frequently with occupants close by, so tidy, well-planned work matters.
Guaranteed is the last step of every job. You get a 12-month guarantee on our workmanship, and the quote explains what it covers.

What sealant work can’t fix
We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:
- Specialist high-level access methods
- Leaks from roofs, gutters or failed flashings rather than sealant joints
- Render or concrete edges that have broken away
Not sure which it is? You can call 01277 525 020 or send photos by email and we’ll tell you honestly.
What we seal
- Perimeter joints where frames meet the structure
- Window and door perimeters
- Stone and brick facade joints
- Coping and flashing joints
- Cladding panel joints
- Shopfront frames
After the work
To get the most from the new sealant:
- Walk the elevations once or twice a year
- Avoid harsh cleaners on facade sealant
- Combine resealing with other works that need access
- Investigate damp beside windows promptly
Include facade joints in your planned maintenance inspections. Watch for splits, gaps at the edges, hardening and discolouration.
Building facade joints into a maintenance cycle avoids emergency repairs. Inspect regularly and reseal sections as they start to fail instead of after the damage.
Common questions from Clay Hill clients
Can you work at a site such as Enfield Retail Park, by Clay Hill?
Yes, sites like Enfield Retail Park are within our area, along with the rest of Clay Hill. To start, just call 01277 525 020 or email a schedule or drawings with the unit, the joints involved and your access times.
Can you cope with the access rules in a London building?
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. The ULEZ covers the whole of Greater London, which we allow for
Will rain stop the work?
Wet joints or temperatures outside the product’s range mean waiting. The programme allows for it and we tell you if the forecast changes things.
Do you seal on top of existing sealant?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.
Can you look at water coming in around a frame?
Yes. Photos help, and you can ring 01277 525 020 or email drawings and photos to arrange a visit. Many frame leaks are sealant failures, though not all, and we’ll be honest about which it is.
Are you fully insured?
Yes. Mastic Doctor is fully insured, public liability included.
Can the sealant be colour-matched?
Often, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We’ll confirm the colours available for the specified product.
Why act early in Clay Hill
Open facade joints also let air and dirt through: draughts around frames add to heating costs and complaints. A new seal closes the gap for both. Failed sealant in a building in Clay Hill can quickly affect neighbours, tenants or the floor below: water travels through shared structures, and a small leak becomes a dispute between occupiers. Dealing with it early is simpler for everyone.
Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.

Different surfaces, different methods
Cladding panel joints
Where panels are sealed rather than open-jointed, the bead is part of the weather line. We cut out failed joints along their full length and rebuild them with backing and a facade-grade sealant.
Render and coated surfaces
Sealant can only hold as well as the render or paint beneath it. We remove flaking material so the bead bonds to a firm surface, and we will mention any edges that need repair.
Building and refurbishing in Clay Hill
Site traffic in Clay Hill falls within London’s ULEZ, like everywhere else in Greater London. Add booked deliveries and tight storage, and the mastic package needs planning with the site team. There are a number of hotels within about 2 miles of Clay Hill. Hotel schemes tend to have fixed reopening dates, so the mastic is programmed tightly with the other trades.
For a contractor working at a hospital such as St Michael's Community Hospital, 0.7 miles to the south of Clay Hill, perimeter and facade sealing is planned around patients and deliveries. Projects at schools like St John's CofE Primary School work to term dates, so mastic is programmed tightly. Hotel extensions and refits, at places such as Holtwhites Hotel (0.9 miles south of Clay Hill), typically run between busy periods, so the sealing is squeezed into short windows.

How a job runs
Before any cutting starts, the area is protected: masking tape along the joint edges and sheeting over anything nearby. On site, the work typically takes longer on a full elevation than on a handful of window perimeters, and it always depends on dry weather, and we clear our waste as we work. For a job in Clay Hill, access comes first. Give us the hours we can be on site and we’ll schedule to suit.
- First we review photographs, drawings or what we saw on a visit, and agree how each joint will be reached.
- Failed sealant is cut out along its full length.
- Both faces are cleaned and, where the product needs it, primed.
- Backing rod, or bond-breaker tape in shallow joints, limits the depth.
- A facade-grade sealant rated for the movement goes in, tooled to a concave profile.
- We walk the finished joints with you before handing over.
Getting the site ready
- Let building users know which areas are affected
- Let us know about inductions and permits
- Arrange parking or a loading space
