FAQs: Dulwich Village
Do you take on jobs in Dulwich Village where loading and access are tightly controlled?
Yes, we plan every London job around the building’s own access rules. The building manager’s rules go straight into our method.
Is Goose Green Trading Estate, near Dulwich Village, within your area?
Yes. Our area takes in Dulwich Village and its surroundings, with estates and business parks such as Goose Green Trading Estate included. Photos and a short description are enough for a first look.
Will residents or tenants be disturbed?
Occupiers stay in the building throughout. We flag any areas that need internal access well before the dates so it can be arranged.
Do you need to see the site first?
It depends on the job. Straightforward work can often be priced from photos and measurements, while larger or less clear jobs get a site visit first.
Which sealant will you use?
The specification comes first, if there is one. Without one, the joint decides: its movement, its surfaces and what it has to cope with.
Can you reseal a whole block or estate?
Yes, planned programmes suit estates and portfolios. You get a fixed quote per building or for the whole job.
What if the old mastic contains asbestos?
In older buildings, old mastic can contain asbestos. We ask for the asbestos register or survey before work starts and suspect material is tested first.
Why deal with it now?
Failed perimeter mastic lets cold air in around frames and the windows normally get the blame. In many cases, new perimeter sealant deals with it where the frames themselves are sound. Repeat call-outs disrupt occupied London buildings, so cutting the old sealant out fully and doing it right once is the better route.
There’s no price list, because the scope varies so much from one building to the next. For a fixed figure, call for a quote and we’ll price your job on its own details.

What else we do in Dulwich Village
What the job involves on each surface
Tenement and older buildings
Stone needs a neutral-cure product, so we pick a grade that won’t mark it.
Commercial and mixed-use buildings
Tenants in commercial buildings need to keep trading so the work is phased.
From enquiry to sign-off
Working in a building that stays open takes some planning. We sign and contain the area we are in, with routes through the building left open and work section by section so the rest of the building stays in use. In Dulwich Village, most buildings stay in use during the work, so zones and timings are agreed with whoever manages the building. Phased work keeps the rest of the building in use.
- We inspect the joints, building by building, and record what has failed and why.
- You get a fixed quote, priced per building where that helps your budgeting.
- Dates, areas and access are agreed so residents or tenants can be told in advance.
- We remove the old mastic completely and clean the joint faces back.
- Backing rod and primer go in where the joint and the product need them, then new sealant is applied and tooled.
- Each building is checked on completion and the work carries our 12-month guarantee.
Getting the site ready

Advice
When to bring in a specialist
Redoing a failed joint normally costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and we’ll confirm the paperwork you need with the quote.
Signs you need mastic sealing in Dulwich Village
We often find joints filled solid with no backing rod, so the mastic is glued to the joint bottom too. That three-sided adhesion stops it stretching and splits as the building moves.
Any of the following is a good reason to get the joints checked over:
- Damaged joints in communal entrances and corridors
- Old repairs sealed over failed mastic
- Repeated reactive repairs to the same buildings
- Draughts at frames across a block
If your remit includes a building such as Dulwich Hamlet Junior School, frame and door mastic can be programmed for the holidays.
