About our facade sealing in South Lambeth
External sealing depends on the weather more than most trades. Joints have to be dry and the air and surface temperature within the product’s range, so frosty or damp mornings can hold work back. We plan for that and keep you updated. Site teams most often ask us about damp patches beside frames after rain and discoloured or dirty facade joints, on stone and brick facade joints, perimeter joints where frames meet the structure and window and door perimeters. Whoever orders the work in South Lambeth, the brief is usually the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
Around South Lambeth, 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.
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.

What sets the cost
Before we quote, we look at:
- Site requirements such as inductions and permits
- How accessible the joints are
- Quantities, in metres or numbers
- Backing rod, priming and other preparation
Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits.
What to include in your enquiry
Diagnosis starts before we arrive. Let us know:
- Any specification or named product
- Whether the building will be occupied during the work
- Approximate linear metres or a joint schedule
- When you need the work done
A good quote starts with a clear picture: what’s there, how much of it, how we reach it and what’s specified. Share whatever details you have and we will fill any gaps with a visit.
Looking after the joints
For the best life from the joints:
- Note when each elevation was last resealed
- Add perimeter sealant to planned maintenance checks
- Check the asbestos register before old mastic is disturbed
- Avoid patch repairs on failed facade joints
After heavy weather, check vulnerable elevations for signs of water inside. An early report typically means a small reseal rather than a bigger repair.
Use each reseal to correct the joint: the right width, backing rod and a sealant with enough movement capability. Repeating a faulty detail just repeats the failure.
What we can’t put right
Part of a good diagnosis is knowing where sealant stops. We’ll tell you if the real problem is any of the following:
- Work on the window or framing system itself
- Joints too narrow for the movement they take, which need redesign
- Leaks from roofs, gutters or failed flashings rather than sealant joints
Not sure which it is? You can ring 01277 525 020 or email us and we will tell you honestly.

Facades, frames and programmes in South Lambeth
The area within 2 miles of South Lambeth holds plenty of hotels. Hotel schemes tend to have fixed reopening dates, so the mastic is programmed tightly with the other trades. Site traffic in South Lambeth falls within London’s ULEZ, like everywhere else in Greater London. Deliveries are booked and storage is tight, so mastic materials come in as needed.
Units on estates such as Handel Business Centre, less than half a mile to the north of South Lambeth, tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal. For contractors on a campus like University of the Arts London (1.1 miles west of South Lambeth), facade and perimeter sealing has to fit around students and term dates. New wings at hospitals like Lambeth Hospital (to the south of South Lambeth) bring long runs of window and panel joints to seal.

How a job runs
When we get to site, we report to your site contact and complete whatever induction the building runs. Floors, finishes and fittings next to the joints are covered before anything is cut or cleaned, and the work typically takes a day or two for a few elevations, and longer where access has to be moved around the building. Planning a London job such as one in South Lambeth starts with access. Give us the hours we can be on site and we’ll schedule to suit.
- Photos, drawings or a visit tell us about the joints and the access.
- We confirm the joint type, movement and the specified product.
- The existing bead comes out in full and both faces cleaned back.
- Primer is applied where the maker specifies it.
- Backing rod is fitted and the new sealant gunned in and tooled.
- The finished joints are checked with you.
Getting the site ready
- Flag any permit to work we’ll need
- Send asbestos survey details if the building is pre-2000
- Send your site hours and access windows

Advice
Why deal with it now?
Failed joints let in more than water: draughts around frames add to heating costs and complaints. A new seal closes the gap for both. Getting scaffold, permits or access booked in South Lambeth takes effort, so while access is arranged it pays to renew all failing joints, not just the worst.
No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.
