Construction mastic in Dulwich Village, done properly
The programme rarely stands still, so the mastic package has to flex with it. The sequence is set with the site team and updated as plots or floors are handed over, so applicators arrive when areas are genuinely ready. That keeps the work right first time and saves rework. If you’re dealing with early adhesion failures on new external joints and perimeter gaps outside the sealant’s range, we can put it right. For commercial sealant work in Dulwich Village, you deal with one contact from quote to sign-off, whether it’s one building or several.
Around Dulwich Village, 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, so tidy, well-planned work matters.
We stand by our work: 12 months, guaranteed. It covers how we prepared and applied the sealant, and we come back if anything isn’t right.

Cost factors for mastic packages
There’s no standard rate for sealant work, since sites vary so much. What we take into account:
- Location, for remote and island sites
- How much there is to seal
- How much existing material needs removing
- Joint width, depth and condition
The price depends on the quantity of joints, what has to come out first and how the joints are reached. Call for a quote once you have the details.
Details that help us quote
A good diagnosis starts with the right details. Tell us:
- Approximate linear metres or a joint schedule
- The postcode of the building
- The asbestos register, for older buildings
- Photos of the joints, close up and from further back
Send us photographs, drawings or a joint schedule and a fixed quote comes back to you. Where a site visit makes more sense, we’ll arrange one.
What happens if it’s left?
On a refurbishment, there’s a choice between resealing existing frames and replacing them. If the frame is in good order, cutting out and resealing the perimeter can be all it needs and that’s a far smaller job. We will say so if a frame itself is the problem. In Dulwich Village, each extra visit means more notices, permits and disruption, so a proper job first time, with the old sealant fully removed, is worth it.
Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits.

Facades, frames and programmes in Dulwich Village
The ULEZ covers the whole of Greater London, Dulwich Village included, so site vehicles need to meet its standards or pay the daily charge. Deliveries are booked and storage is tight, so mastic materials come in as needed. There are plenty of hotels within about 2 miles of Dulwich Village. Hotel refurbishments often run to tight programmes between busy periods, and perimeter and sanitary sealant has to keep up.
For contractors at a school such as Dulwich Hamlet Junior School, sealing has to be finished before term starts. Projects at colleges like William Booth College (1.2 miles north of Dulwich Village) tend to run to term dates, so the mastic is planned tightly. New units and refits on sites such as Goose Green Trading Estate, 0.9 miles to the north-east of Dulwich Village, need their panel and perimeter joints sealed to the specification.

Questions about Dulwich Village
Can work at a site such as King's College London fit around teaching?
Yes. Tell us the term dates, vacation periods and access windows, and we will plan the work around them. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.
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. A few photographs and the unit address let us price the work.
What if there’s asbestos in the old mastic?
The duty to manage asbestos sits with the building’s dutyholder, so we’ll ask for the register before work on an older building. If anything suspect turns up, we stop until it’s tested.
Is Dulwich Village in your area?
Yes. Sites across Dulwich Village are covered, with one number for every area we cover.
What about RAMS and site documents?
Requirements differ from site to site, so list what you need, whether RAMS, insurance or CSCS details, and we’ll confirm with the quote.
Can you fit around our working hours?
Give us your site hours and any access windows in your enquiry, and we’ll plan around them. You can reach the office between 8am and 5pm, Monday to Friday.
Is the mastic package guaranteed?
Our workmanship carries a 12-month guarantee from sign-off. The guarantee covers our work, not later damage by other trades.
What we can’t put right
A proper diagnosis includes knowing what sealant can’t do. We’ll tell you if the real problem is one of these:
- Glazing units that are cracked or misted
- Fire-stopping design or sign-off (that’s for the designer, fire engineer and building control)
- Joint design decisions that belong to the architect or engineer
Not sure which it is? You can ring 01277 525 020 or email the details over and we’ll tell you honestly.

Where the sealant needs time to cure before use, we tell you and sign the area.

Doing it in-house
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 our CSCS-carded applicators are used to working under those rules.
