About our construction mastic in Peckham
Mastic is often where a new building first shows its quality to the client. A smeared bead round a window or a gap behind a worktop ends up on the snag list and clearing them late eats into the handover window. We seal so the snag list stays short. If you have old sealant on a refurbishment that needs stripping before new work and sanitary sealant damaged by following trades, we can put it right, whatever the surface. Facilities teams, main contractors and managing agents in Peckham 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.
A 12-month guarantee applies to all our work in Greater London. Should something we installed fail, ring 01277 525 020 or email a schedule or drawings and we’ll come back to it.

When to bring in a specialist
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.
A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
What the job involves on each surface
Internal decorators’ caulk
Acrylic caulk fills internal gaps around trims, boards and frames ahead of decorating. It’s paintable and suits gaps that don’t move.
Bathrooms, en suites and washrooms
On multi-unit schemes, consistency matters across hundreds of bathrooms. One applicator team gives the same finish everywhere.
What affects the price in Peckham
Each job is priced on its own details. The main factors are:
- Removal of failed or old sealant
- Travel to remote or island sites
- Specialist products, such as fire-rated or hygienic sealants
- How accessible the joints are
Small jobs and large programmes are priced from the same things: 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.
Details that help us quote
We can often quote from photographs and a few details. It helps to include:
- The type of building and who uses it
- The site address and postcode
- Approximate linear metres or a joint schedule
- How the joints are reached, and at what height
Let us know the site, the scope and your timescale, and a fixed quote will follow. The easiest way is to phone 01277 525 020 or send photos by email.
How a job runs
Working in a building that stays open takes some planning. We sign and contain the area we’re in, with routes through the building left open and move on in phases so staff and visitors can carry on around us. In Peckham, most buildings stay in use during the work, so zones and timings are agreed with whoever manages the building. Areas are handed back as each section is finished.
- We price from the drawings, specification and programme you send.
- You receive a fixed quote listing scope, products and phasing.
- Any site paperwork you need (RAMS, insurance certificate, CSCS details) is confirmed with the quote.
- Areas are sealed plot by plot or floor by floor as the trades hand them over.
- Every joint is prepared, set to depth and sealed with the specified product.
- Before handover, snags are dealt with and the package is signed off under our 12-month guarantee.
Before we start on site
- Clear stock, furniture or equipment away from the joints
- Tell us what induction or permit system the site runs
- Point out any areas we must not close

Who decides which product is used?
A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
Can you clear a mastic snag list before handover?
Yes. We clear snags by redoing joints rather than patching them.
Will you come and look before quoting?
Photos, drawings or a schedule are often enough to quote. Where they aren’t, we arrange a site visit.
Do your applicators hold CSCS cards?
We’re CHAS accredited and a Constructionline member, and our applicators hold CSCS cards. We confirm any paperwork you need with the quote.
For managing agents and facilities managers
Facilities managers want contractors who arrive with the paperwork sorted. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm with the quote.
When you manage a building on behalf of an owner, you need clear quotes and clear reporting. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative, plus a 12-month guarantee.

Construction mastic in Peckham: the local picture
Peckham has a good number of hotels close by, all within 2 miles. When hotels extend or refit, the work is typically squeezed between peak periods, mastic included. As part of Greater London, Peckham 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.
For contractors at a college like Christ the King: Aquinas Sixth Form College, 1 mile to the east of Peckham, perimeters and internal sealant are timed for the holidays. On a healthcare site such as Maudsley Hospital, 1.2 miles west of Peckham, new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully. For contractors on a campus like King's College London, 1.3 miles west of Peckham, facade and perimeter sealing has to fit around students and term dates.
Peckham is about 2 miles south-east of London, in Greater London. Anywhere in SE15, it works the same way: send details, get a fixed quote, we seal, and the work is guaranteed. 764 places across Greater London fall within our area, Peckham among them.
