Facade sealing in Brockley Hill, done properly
Water ingress at window frames is a frequent reason facilities managers contact us. Failed perimeter sealant is a frequent cause, but not always. We’ll tell you if we think the leak is coming from somewhere sealant won’t fix. If you have gaps between rainscreen or cladding panels and failed seals around shopfront and entrance frames, we can put it right. Facilities teams, main contractors and managing agents in Brockley Hill tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.
A great deal of London construction is refurbishment of occupied or part-occupied buildings, alongside new blocks. Replacement windows, recladding and fit-outs leave perimeter and facade joints to seal, often next to people still using the building.
The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Common questions from Brockley Hill clients
Could you schedule work at a campus like Middlesex University for the vacation?
Yes. Education sites typically want the work in vacations or in phases during term, and we plan to suit. We’re CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.
Is Lismirrane Industrial Park, near Brockley Hill, within your area?
Yes. Our area takes in Brockley Hill and its surroundings, with estates and business parks such as Lismirrane Industrial Park included. Photos and a short description are enough for a first look.
What type of sealant goes on window perimeters?
Low-modulus, neutral-cure silicone suits many facade and perimeter joints. Hybrid or MS polymer, polyurethane and polysulphide sealants suit others, as the specification or substrate requires.
Can you work on upper floors?
That comes down to the access arranged for the job. When you call 01277 525 020 or use the quote form, describe the access, and we’ll agree the approach together.
Are you insured?
Yes. Our insurance certificate can be sent alongside the quote.
Do you replace failed glazing units?
No. A glazing contractor handles that. What we seal are the joints around frames and panels.
Can you quote from photographs?
That depends on the size and complexity of the job. Simple work can often be priced from photographs, while larger or less clear jobs get a site visit first.
What the job involves on each surface
Brick and stone facades
Brick and stone facades have perimeter and movement joints that need a compatible sealant. Neutral-cure products are used because acetoxy types can mark some stone.
Render and coated surfaces
Where the joint will be painted over, a paintable hybrid or PU sealant may suit. The choice depends on the specification and finish.
Quoting for work in Brockley Hill
Your fixed quote is built from the real scope. It takes account of:
- The site’s rules and procedures
- Phasing around occupants
- The total length or number of joints
- Which sealant the job calls for
Whether it’s a single area or a whole estate, the same things set the price: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote and we will put a fixed figure on it.
What we need to price the job
However big the job, these details speed things up:
- When you need the work done
- Specification clauses that apply
- The site address and postcode
- Whether the building will be occupied during the work
We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To ask for one, ring 01277 525 020 or email us.
When to bring in a specialist
Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we’ll confirm the paperwork you need with the quote.
From enquiry to sign-off
A typical day starts with protection: tape along each joint edge and covers over finishes, stock and equipment close by. The work itself usually takes longer on a full elevation than on a handful of window perimeters, and it always depends on dry weather, and our waste is bagged and taken away as we go. Planning a London job such as one in Brockley Hill starts with access: 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.
- The old bead is cut away completely, not overlaid.
- 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.
Getting the site ready
- Point out any areas we must not close
- Have the specification and drawings to hand
- Share your working hours and any access restrictions

Building and refurbishing in Brockley Hill
A 2-mile radius around Brockley Hill takes in several hotels. Hotel schemes tend to have fixed reopening dates, so the mastic is programmed tightly with the other trades. Every borough of Greater London is inside the ULEZ, and that applies to contractors’ vehicles on any job in Brockley Hill. Deliveries are booked and storage is tight, so mastic materials come in as needed.
Extensions at sites like Royal National Orthopaedic Hospital (0.5 miles west of Brockley Hill) normally sit beside working departments, and the mastic follows strict access rules. For contractors on a campus like Middlesex University (3.4 miles south-east of Brockley Hill), facade and perimeter sealing has to fit around students and term dates. For a contractor at a hotel such as Edgwarebury Hotel and Restaurant, 0.8 miles north-east of Brockley Hill, the mastic often has to be finished before a reopening date.

Maintenance after handover
Once the work is signed off, a little attention goes a long way:
- Confirm the survey covers external sealants in older buildings
- Investigate damp beside windows promptly
- Never let anyone seal over old sealant
- Inspect facade joints on a regular cycle
After heavy weather, check vulnerable elevations for signs of water inside. An early report typically means a small reseal rather than a bigger repair.
Don’t wait for a full elevation to fail. Small repairs stop small leaks becoming large ones inside the building.
