Why act early in Crayford
Patch repairs over old sealant tend to come back. A full cut-out and reseal costs more on the day but lasts much longer, so you aren’t paying for the same joint twice. In a London building, a failed joint rarely affects only one party. Dealing with it early is simpler for everyone.

Facade sealing in Crayford
Managing agents and owners in Crayford ask us to, we reseal perimeters across whole elevations or a handful of problem windows. The approach doesn’t change with the size: cut out, clean, back, prime where needed and seal. A 12-month guarantee applies to our workmanship. Site teams most often ask us about air leaks through failed facade joints and new sealant peeling off old mastic, across window and door perimeters, stone and brick facade joints and coping and flashing joints. Facilities teams, main contractors and managing agents in Crayford tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
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.
The 12-month guarantee covers our workmanship: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Signs you need facade sealing in Crayford
New sealant run over old sealant rarely holds. Fresh silicone won’t stick to cured silicone.
Typical triggers for a call:
- Failed sealant on precast panel joints
- Patch repairs that keep failing
- Leaks at window and door perimeters
- Old perimeter mastic that has dried out
When a college such as North Kent College, 1.5 miles south-east of Crayford, builds or refurbishes, the mastic package usually has to fit around students and staff.
What your quote should include
- Whether primer will be used where the manufacturer specifies it
- The named product and why it was chosen
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
- What level of public liability insurance do they hold?
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 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. For a job in Crayford, access comes first: booked loading, goods lifts, the building’s permit system and a spot to keep materials. Send the building rules and access times with your enquiry.
- We look at the joints, the drawings and the access before pricing.
- Failed sealant is cut out along its full length.
- Both faces are cleaned and, where the product needs it, primed.
- Closed-cell rod fixes the depth, and the sealant grips two sides only.
- A facade-grade sealant rated for the movement goes in, tooled to a concave profile.
- The completed runs are checked with you, then the 12-month guarantee applies.
What we need from you
- Tell us which areas need to stay in use
- Have the specification and drawings to hand
- Send asbestos survey details if the building is pre-2000
Quotes
Photos, drawings or a schedule of the joints are often enough for a fixed quote. Where a site visit makes more sense, we will arrange one.

Building and refurbishing in Crayford
Every borough of Greater London is inside the ULEZ, and that applies to contractors’ vehicles on any job in Crayford. London sites also mean booked deliveries and limited storage, which the mastic programme has to allow for. Crayford has several hotels close by, all within 2 miles. Hotel refurbishments often run to tight programmes between busy periods, and perimeter and sanitary sealant has to keep up.
University estates such as University of Greenwich, 3.8 miles to the east of Crayford, tend to have a rolling programme of new buildings and refurbishments, each with window perimeters and facade joints to seal. For a contractor at a hotel such as Bexleyheath Marriott Hotel, 1.3 miles west of Crayford, the mastic often has to be finished before a reopening date.

Questions about Crayford
Do you cover business parks and estates near Crayford, such as Tower Retail Park?
Yes. We cover Crayford and the area around it, including industrial estates, business parks and retail parks such as Tower Retail Park. Send details of the unit and the work through our quote form for a quick quote.
Can work at a site such as University of Greenwich fit around teaching?
Yes, holiday working periods are the norm on campus jobs. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.
Do you seal facades in winter?
Year-round work is possible as long as joints are dry and temperatures suit the product. Frost and condensation on glass and steel are common on winter mornings.
Will your applicators have CSCS cards?
Yes. We use CSCS-carded applicators.
Is your workmanship covered by a guarantee?
Yes. It runs for twelve months and covers how we prepared and sealed the joints, though not damage or work by other trades.
Who decides which product is used?
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.
What about RAMS and site documents?
Each site asks for different documents, so list what you need, whether RAMS, insurance or CSCS details, and we will confirm with the quote.
Cost factors for facade joints
Your fixed quote is built from the real scope. It takes account of:
- The site’s rules and procedures
- The product specified
- Quantities, in metres or numbers
- Phasing around occupants
Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.
Before you send an enquiry
Good information means a firmer quote. When you get in touch, include:
- Any specification or named product
- The postcode of the building
- Your programme or deadline
- Approximate linear metres or a joint schedule
We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To start the process, ring 01277 525 020 or use the quote form.
Should maintenance staff do it?
The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.
There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we will confirm the paperwork you need with the quote.
