Commercial mastic work in East Dulwich
If you look after more than one building, a single sealant contractor saves a lot of chasing. Single jobs, multi-site packages and planned programmes all come to us: send details, get a fixed quote, we seal, and a 12-month guarantee once it’s signed off. For sites in East Dulwich, the quickest start is to call 01277 525 020 or send details through our quote form with a list of addresses. Site teams most often ask us about expansion joints with the sealant torn out and a top-up bead over failed sealant, now lifting, across washrooms and tea points, kitchen worktops and splashbacks and window and door perimeters. For commercial sealant work in East Dulwich, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.
We price commercial jobs in East Dulwich from photos, drawings or a site visit, and the scope is set out in writing.
London’s commercial stock mixes period buildings turned into offices with modern glass and steel, which means one visit can cover joints against stone, brickwork, coated aluminium and shop-fit panels. Each surface gets its own preparation and, where it’s seen, a sealant colour that sits with it.
The 12-month guarantee is for workmanship rather than wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we are clear about what is covered before work starts.

Leave it or put it right?
Sealant is often treated as an afterthought by the trade that fitted the element. Choosing the product, setting the depth and preparing the faces are what a specialist brings, the three things that decide how long a joint lasts. It shows over the following seasons rather than at handover. In a London building, a failed joint rarely affects only one party: water travels through shared structures, and a small leak becomes a dispute between occupiers. Putting it right early is less disruptive than dealing with the consequences.
Every site prices differently: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.

On site: what to expect
Working in a building that stays open takes some planning. The work area is signed and kept contained, with routes through the building left open and work section by section so the rest of the building stays in use. All of Greater London is in the ULEZ, and kerbside space in East Dulwich can be scarce. If there’s a loading bay, a car park or a permit we can use, tell us when you send details.
- Site photos, drawings or a visit tell us what’s there and how it has failed.
- You get a fixed quote covering removal, preparation and the new sealant.
- Sequence, access and working times are settled before the first joint is touched.
- Each joint is stripped, cleaned back to sound faces and primed where the maker specifies.
- Backing goes in, the new sealant is laid and tooled, and the area is left neat.
- We hand back each area with its cure time and our 12-month guarantee.
Getting the site ready
- Tell us which areas need to stay in use
- Tell us what induction or permit system the site runs
- Share your working hours and any access restrictions
Quotes
Every quote starts with the facts: the joints involved, quantities, access and the product called for. Send what you have, and we will arrange a site visit if anything is unclear.
Advice
How the job changes by surface
Fire-rated seals where specified
Not every penetration suits a sealant. Collars, wraps, batts and boards are specified for other services and gaps, so we will flag it if the detail needs a different product.
Facade and cladding joints
Panel joints on cladding and rendered facades open and close with the temperature. They need a sealant with the right movement capability, laid at the right depth. Access, such as scaffold already up, is agreed before the price is fixed.
When something else is needed
Some faults sit outside our scope, and we say so rather than covering them up:
- Water from a services leak rather than a joint
- Old mastic that tests positive for asbestos
- Faulty windows rather than failed perimeter sealant
If you’re not sure, just ring 01277 525 020 or email drawings and photos and we’ll give you a straight answer.
What we seal
- Movement joints in walls and floors
- Kitchen worktops and splashbacks
- Floor and threshold joints
- Washrooms and tea points
- External facade joints
- Window and door perimeters
When to bring in a specialist
The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.
For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.
Keeping the joints sound
Problems stay small when the joints are checked regularly. In particular:
- Keep abrasive pads and scrapers off resealed joints
- Keep a record of which joints were resealed and when
- Have extract fans checked so wet areas dry out
- Look at the sealant around anything that has been moved or replaced
Our workmanship on each job is backed by a 12-month guarantee. Keep the handover details with your O&M or maintenance records so it’s easy to find if a joint we sealed gives trouble inside the 12 months.
Tenants and staff spot black or split sealant quickly. Replacing it on a planned cycle keeps complaints down.
Questions we’re asked in East Dulwich
Do you take on jobs in East Dulwich where loading and access are tightly controlled?
Yes, we plan every London job around the building’s own access rules. Say when the building is occupied and when it’s quiet, and we’ll plan accordingly. All of Greater London is inside the ULEZ, and our planning allows for it
Do hotels near East Dulwich have to close for sealant work?
Rarely. Rooms or floors are done in turn, so the rest of the hotel keeps trading. Housekeeping and our team agree each day’s rooms.
Can you supply RAMS and insurance details?
We will confirm the paperwork you need, such as RAMS, an insurance certificate or CSCS details, with the quote. We are CHAS accredited and a Constructionline member, with five million pounds of public liability insurance.
Do your applicators hold CSCS cards?
Yes. We use CSCS-carded applicators, as many construction sites ask for.
Does commercial sealant work come with a guarantee?
Each job sits under our 12-month guarantee. Keeping joints clean and inspected helps them last well beyond that.
Are you CHAS accredited and on Constructionline?
Yes. We are CHAS accredited and a Constructionline member, which helps with supplier vetting.
How long does a job like this take?
That varies with the scale of the job, though a typical visit normally takes as long as the agreed scope needs, from a single visit to a programme spread over several weeks. Larger or phased jobs take longer, and we’ll give you a timescale with the quote.
Working on commercial sites near East Dulwich
There are a good number of hotels within about 2 miles of East Dulwich. A hotel refurbishment is full of joints that guests will see, and a matched colour keeps them discreet, with rooms done in turn while the rest stay let. In London, commercial buildings often have managed loading bays, goods lifts and permit-to-work systems. Our planning starts from those rules rather than working round them later.
A business with units at Goose Green Trading Estate and Bellenden Road Business Centre needn’t use two contractors for its sealant. In hotels such as OYO New Dome Hotel, 0.9 miles to the north of East Dulwich, refurbishments typically mean bathroom, bar and reception joints where a matched sealant colour has to sit with the finishes. For premises near East Dulwich station, under half a mile to the south-east of East Dulwich, footfall is part of the plan: work is phased so shops and offices keep trading.
