Facade sealing for commercial buildings in South Kenton
We seal window and door perimeters, cladding panel joints, external facade joints and perimeter joints where frames meet the structure on offices, blocks and industrial units. Where sealant is the specified fix, we also take on coping and flashing joints. If you are dealing with perimeter joints where frames meet the structure and previous reseals run over old sealant, we can help. Searching for sealant specialists in South Kenton? Mastic Doctor has worked for contractors, FMs and building owners since 2005, with CSCS-carded applicators.
A great deal of London construction is refurbishment of occupied or part-occupied buildings, alongside new blocks. New frames, overcladding and fit-outs all end in perimeter and facade joints, frequently with occupants close by, so tidy, well-planned work matters.
We sign every job off with a 12-month guarantee. The promise is simple: if our work fails within that year, we put it right.

Leave it or put it right?
Topping up a failed joint usually buys very little time. A full cut-out and reseal costs more on the day but lasts much longer and avoids repeat call-outs. Access in London is hard enough to arrange once, so while access is arranged it pays to renew all failing joints, not just the worst.
The specified product makes a difference, as does the preparation each joint needs. Access, phasing and site requirements come into it too.

Our process
Before any cutting starts, the area is protected: tape along each joint edge and covers over finishes, stock and equipment close by. On site, the work normally takes a day or two for a few elevations, and longer where access has to be moved around the building, and our waste is bagged and taken away as we go. The ULEZ covers the whole of Greater London, and parking near a job is rarely simple. If there’s a loading bay, a car park or a permit we can use, tell us when you send details.
- Access, site rules and timing are settled with the client up front.
- Weather and temperature are checked against the product’s limits.
- We remove the old bead and check the edges are sound.
- Faces are cleaned, primed where needed and backed.
- Facade-grade sealant goes in and is tooled to a tidy concave profile.
- We hand over with our 12-month workmanship guarantee.
Getting the site ready
- Have the specification and drawings to hand
- Arrange parking or a loading space
- Warn occupants and staff about the work

Aftercare for building managers
Every sealant joint needs some looking after, and how long they last depends on how they’re treated. Our advice:
- Insist on a full cut-out when joints are renewed
- Walk the elevations once or twice a year
- Keep sills, gutters and drainage paths clear
- Avoid harsh cleaners on facade sealant
Blocked sills and gutters push water at the joints. Good drainage keeps water moving off the facade instead of soaking the joints.
Don’t wait for a full elevation to fail. A few metres resealed promptly can stop water damage spreading behind the facade.
New build and refits around South Kenton
As part of Greater London, South Kenton is inside the ULEZ, which applies to every van on site. Add booked deliveries and tight storage, and the mastic package needs planning with the site team. A 2-mile radius around South Kenton takes in a good number of hotels. Hotel extensions and refits typically have to fit around bookings, so mastic dates are tight.
Projects at colleges like London College of Management Studies (to the north of South Kenton) tend to run to term dates, so the mastic is planned tightly. For contractors refurbishing units at places like East Lane Business Park, which lies south-east of South Kenton, the mastic covers cladding panels, roller-door and window perimeters. New wings at hospitals like Northwick Park Hospital (to the north-west of South Kenton) bring long runs of window and panel joints to seal.

How the quote is worked out
To price the job, we consider:
- Any access equipment needed
- Quantities, in metres or numbers
- Specialist products, such as fire-rated or hygienic sealants
- Location, for remote and island sites
There’s no price list, because the scope varies so much from one building to the next. Call for a quote.
What we need to price the job
The more we know, the firmer the quote. When you get in touch, include:
- Whether an asbestos survey exists
- Drawings or a marked-up plan, if available
- When you need the work done
- Access details, including height
We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To ask for one, phone 01277 525 020 or email the details over.
Should maintenance staff do it?
For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
Certain joints really need a specialist: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong typically costs more in the end than doing them right.
Questions we are asked in South Kenton
Can you work at a site such as East Lane Business Park, by South Kenton?
Yes. Estates, retail parks and business parks around South Kenton, East Lane Business Park among them, are all within reach. Send details of the unit and the work through our quote form for a quick quote.
Can work at a site such as Westminster University fit around teaching?
Yes. Tell us the term dates, vacation periods and access windows, and we’ll plan the work around them. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.
Do you have public liability insurance?
Yes. We are fully insured, and the certificate can go with your quote.
How long do sealant joints last?
There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.
Do you replace windows or glass?
No. A glazing contractor handles that. What we seal are the joints around frames and panels on commercial buildings.
Are you CHAS accredited and on Constructionline?
Yes. We’re CHAS accredited, we are a Constructionline member and we use CSCS-carded applicators.
Should we check old sealant for asbestos?
Some older mastics, especially in pre-2000 buildings, can contain asbestos. The dutyholder’s asbestos register should be checked first; if it’s suspected, work stops until it has been tested. We don’t remove asbestos-containing materials.
When it isn’t the sealant
A few problems need another trade or a different fix, and we say so rather than covering them up:
- Replacing glass or failed glazing units
- Joints whose design needs changing by the specifier
- Leaks from roofs, gutters or failed flashings rather than sealant joints
If in doubt, call 01277 525 020 or email us and we’ll say what we think.
