What Forest Gate’s businesses ask us to seal
Forest Gate has at least three named business or industrial parks inside a 3-mile radius. Units on sites like these change tenants and get refitted, and each refit leaves joints to seal, often in a colour the occupier specifies. A 2-mile radius around Forest Gate takes in plenty of hotels. Refits in hotels bring joints at vanity tops, bar counters and reception desks where the colour has to suit the scheme.
Shopping centres and retail parks such as Stratford Centre (to the south-west of Forest Gate) see a steady turnover of shop fits, each leaving joints where colour and finish matter. For premises near Wanstead Park station, under half a mile to the north-west of Forest Gate, footfall is part of the plan: work is phased so shops and offices keep trading.

Commercial mastic work in Forest Gate
We’ve applied sealant on commercial sites for over 20 years, and the documents buyers ask for are ready: we are CHAS accredited and a Constructionline member, our applicators hold CSCS cards, and we carry five million pounds of public liability insurance. If your site needs RAMS, an insurance certificate or CSCS details, say so and we will confirm with the quote. We work on movement joints in walls and floors, kitchen worktops and splashbacks and washrooms and tea points, and the usual reasons a site gets in touch are smeared sealant across finishes from a rushed job and greasy, split joints in a kitchen or tea point. Searching for sealant specialists in Forest Gate? We’ve been sealing commercial buildings since 2005, with CSCS-carded applicators.
Quotes for commercial sealant in Forest Gate can come from photos and a joint schedule, or from a walk-round, 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.
Whoever the client is, the cover is the same: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Forest Gate: questions and answers
Can you work in a London building with booked loading and goods-lift slots?
Yes. Inductions, permits and timed loading are routine for us in London. Say when the building is occupied and when it’s quiet, and we’ll plan accordingly.
Must a hotel around Forest Gate close while you work?
Rarely, if ever. We take a few rooms out at a time. The plan is built around your bookings.
Do you check for asbestos before removing sealant?
It can, on some older buildings. So we check the register first and stop work on anything suspect until it’s tested.
Do you cover Forest Gate?
Yes. We cover Forest Gate and the rest of Greater London, within our coverage of Greater London, South East England and Scotland. For a quote, phone 01277 525 020 or email us.
Is the old sealant taken out first?
Full removal is part of every quote. Sealing over traps water and lifts once the joint moves and isn’t worth paying for.
Are you CHAS accredited?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member.
Can you work to our specification?
Yes. Send it with your enquiry, and we’ll price the work to it, flagging anything that needs clarifying.
What sealant work can’t fix
We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:
- Water from a services leak rather than a joint
- Roof leaks that only look like a joint problem
- Cracking that needs a structural engineer to look at it
If you are not sure, just phone 01277 525 020 or email a schedule or drawings and we’ll give you a straight answer.
Surfaces we seal
- Kitchen worktops and splashbacks
- Floor and threshold joints
- Movement joints in walls and floors
- Window and door perimeters
- External facade joints
- Washrooms and tea points
Our process
We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. Most London premises stay occupied while we are on site, so we agree zones and timings with the building or facilities manager. Areas are handed back as each section is finished.
- We start with the evidence: photos, drawings or a look on site.
- A fixed quote follows, with removal and preparation included.
- We agree the order of work, access windows and site hours with you.
- Each joint is stripped, cleaned back to sound faces and primed where the maker specifies.
- Depth is set with backing, then the sealant is applied, tooled and the area tidied.
- Completed areas are signed off with you under our 12-month guarantee.
What we need from you
- Arrange parking or a loading space
- Tell staff and tenants when we will be in
- Tell us which areas need to stay in use
Quotes
Photos, drawings or a schedule of the joints and a fixed quote comes back to you. If the job needs a look first, we’ll arrange a site visit.

When to call us in Forest Gate
Every sealant joint is a maintenance item. Its life comes down to movement, UV and weather, how it’s cleaned, how much traffic passes it and what was used in the first place. In commercial buildings those factors tend to act together, which is why regular inspection pays.
Things that usually lead to an enquiry:
- Hardened, chalky sealant on south-facing or exposed elevations
- Earlier reseals applied straight onto the failed bead
- Untidy joints in a reception, shop floor or lobby
- Frame sealant that has cracked, shrunk or pulled away
For tenants and agents on sites such as Acacia Business Centre, 1 mile north-west of Forest Gate, office fit-outs, reception joints and window perimeters are the usual sealant work.
Questions to ask before you book
- The terms of the workmanship guarantee
- How joint depth will be controlled
- How the existing material will be dealt with
- Which product they’ll use, and why it suits the joint
General trades versus 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.
Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
Surface by surface
Fire-rated seals where specified
Intumescent and other fire-rated sealants go in at service penetrations and linear gaps to the maker’s tested details, where they are specified. The design and sign-off of fire stopping belong to the designer and building control; we install what’s specified.
Washrooms and toilets
Black sealant in a toilet block is normally beyond cleaning. The lasting answer is removal, preparation and a new sanitary bead.
