Commercial sealant contractors in TW12: how it works
Mastic Doctor has been sealing joints for businesses and contractors since 2005: CHAS accredited, Constructionline member, five million pounds of public liability insurance and CSCS-carded applicators. Let us know which site documents you need and they’ll be confirmed with the quote. We work on kitchen worktops and splashbacks, window and door perimeters and floor and threshold joints, and the failures we’re asked to look at most are damp patches where an external joint has failed and greasy, split joints in a kitchen or tea point.
Diagnose, treat, sign off: every visit follows that pattern. First comes an inspection and agreement on scope, then the work is carried out to the specified product and detail, and the job ends with a walk round and sign-off.
- Send details through our quote form, or ask for a site visit.
- We diagnose the cause of failure and price a fixed scope.
- Where parts of the building must stay open, the work is phased.
- Every failed bead is removed rather than covered.
- Each joint gets a suitable sealant, laid to depth and tooled.
- We check the work with you, and the 12-month guarantee starts.
How we quote
No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.

Commercial sealant contractors across TW12: the area picture
From Teddington, Hampton and Hanworth outwards, TW12 has a broad spread of commercial premises: shops, offices, hotels, restaurants and units. Because we cover all of it, multi-site occupiers can bring every building under one quote.
London and the South East are among the drier parts of the UK, though outside work in TW12 still waits for dry faces, and cold mornings bring frost and condensation on steel and glass.
Hampton: Like every part of Greater London, Hampton is covered by the ULEZ, so vehicle access, loading and parking are planned before the first visit. Occupiers with premises at both Kingsway Business Park and Longford Industrial Estate could have the sealant at each handled under one quote.
When to bring in a specialist
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.
The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.
When something else is needed
Some faults sit outside our scope, and we point that out rather than sealing over them:
- Removing asbestos-containing materials (a licensed or specialist contractor’s job)
- Structural cracks or movement the joints weren’t designed for
- Leaking roofs, gutters or flat-roof membranes (those need a roofer)
Looking after the joints
Cleaning and maintenance staff play a part too. Share these points with them:
- Check the asbestos register before anyone disturbs old sealant in an older building
- Act on the first lifting edges rather than waiting
- Keep a record of which joints were resealed and when
- Put external and wet-area joints on a regular inspection round
Let your cleaning contractor know what’s new. Abrasive pads, scrapers and some strong chemicals damage sealant surfaces; a mild cleaner is all most joints need.
Movement joints that fill with debris stop working. The joint can no longer close, so its edges crack or spall. That turns a sealant job into something bigger.
What we’re called out for in TW12
A good share of the joints we inspect were topped up instead of being renewed. Fresh sealant won’t stick to the old bead underneath. By the time it shows, there can be two or three layers to cut out.
Typical triggers for a call:
- Black mould through washroom sealant that won’t clean off
- Smeared sealant across finishes from a rushed job
- Weathered facade sealant that no longer flexes
- Window and door perimeter joints that have cracked open
Leave it or put it right?
Some managers wait for a fit-out before touching the mastic. That’s reasonable for internal joints that are just tired-looking, but a joint letting water in now keeps doing damage until the refurb arrives. Splitting the scope into now and later is often the sensible compromise.

Questions about TW12
Do you check for asbestos before removing sealant?
It’s possible in older buildings, especially those built before 2000. We ask to see the asbestos register or survey before disturbing old sealant, and anything suspect is left until it has been tested.
How soon can the area be used again?
That comes down to the sealant and the temperature. Some take light use quickly, others need longer to cure, so we’ll confirm the curing time on the day.
Can areas stay open during the work?
Phased work can be planned so areas stay in use. We plan around the site hours and access windows you give us.
Which site documents can you send us?
Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote. We are CHAS accredited and a Constructionline member, with five million pounds of public liability insurance.
Will you just go over the old sealant?
No. We cut the old material out and clean the joint back before sealing, since fresh sealant will not bond reliably to aged material.
Is it OK to apply fresh sealant over existing beads?
The old bead is stripped out first. Then the joint is cleaned, primed where the maker specifies, backed to depth and resealed.
How long does a job like this take?
It depends on the scope, though a typical visit normally takes anything from part of a day on a short run of joints to several weeks on a large phased package. Larger or phased jobs take longer, and we’ll give you a timescale with the quote.
