How we handle commercial sealant contractors in Turnham Green
Most commercial buildings carry hundreds of metres of sealant that nobody thinks about until it fails. Mastic Doctor works as a commercial sealant contractor for facilities managers, managing agents and main contractors. Our job is to diagnose the failure, remove the old bead and seal again using a product chosen for the movement and exposure. If you have shrunken sealant along kitchen worktops and splashbacks and external beads that have gone brittle and cracked, we can put it right, on kitchen worktops and splashbacks, window and door perimeters and movement joints in walls and floors alike. Searching for sealant specialists in Turnham Green? Mastic Doctor has worked for contractors, FMs and building owners since 2005, CHAS accredited and a Constructionline member.
If you look after more than one building near Turnham Green, the work can be planned as one programme, with one quote format and one point of contact.
London’s commercial stock mixes period buildings turned into offices with modern glass and steel, so one job can involve stone, brick, powder-coated frames and laminate in a single visit. Each surface gets its own preparation and, where it’s seen, a sealant colour that sits with it.
Building owners and contractors get the same cover: twelve months on the work we carried out. It doesn’t extend to damage, faults in the building or work by others, and we’re upfront about that.

Signs you need commercial sealant contractors in Turnham Green
Resealing over the top is a false economy we come across often. New silicone has nothing to key into. By the time it shows, there can be two or three layers to cut out.
Common reasons buildings call us in:
- Untidy joints in a reception, shop floor or lobby
- Greasy, split joints in a kitchen or tea point
- Frame sealant that has cracked, shrunk or pulled away
- Earlier reseals applied straight onto the failed bead
Turnham Green is inside London’s ULEZ, as is the rest of Greater London; tell us about loading bays, goods lifts and parking when you send details.
What your quote should include
- Can the work be phased to keep areas open?
- How long is the guarantee, and what does it include?
- Will RAMS and insurance details be available?
- How the existing material will be dealt with
What Turnham Green’s businesses ask us to seal
Less than 3 miles from Turnham Green there are at least three named estates and business parks. Tenant changes on such sites bring fit-outs, and fit-outs bring new joints. 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.
Shop fits at places like Kew Retail Park, 1.2 miles to the south-west of Turnham Green, leave counters, frontages and floor edges where the sealant colour is part of the finish. A hotel such as Chiswick Lodge Hotel, 0.6 miles north of Turnham Green, shows how much sealant a hospitality building has on show, from bathroom joints to the bar.

Maintenance after handover
Regular inspection catches problems early. Specifically:
- Brief cleaning contractors to avoid scourers and blades on sealant
- Check sealant as part of routine building inspections
- Make sure contractors see the asbestos survey before cutting out old mastic
- Respect the cure time before reopening an area
Keep an eye out for other trades after we have gone. Shop refits, new services and replaced fittings often break the seal around them, and it’s easy to forget to reseal afterwards. Where work has disturbed a joint, just give us a call on 01277 525 020 or email a schedule or drawings for a quote.
Occupiers often notice failing sealant before the facilities team does, and it reflects on how the building is run. Replacing it on a planned cycle keeps complaints down.
Surface by surface
Washrooms and toilets
Mould that has grown into washroom sealant can’t typically be cleaned out. Replacement is the fix: strip, clean, dry and reseal.
Window and door perimeters
Where frames meet the surrounding wall, sealant is the weather line. Failed perimeters are cut out and cleaned, backing goes into deeper gaps, and the joint is resealed with a low-modulus neutral-cure silicone or another suitable product.
Turnham Green: questions and answers
Will our hotel in Turnham Green need to close for the work?
Rarely. Rooms or floors are done in turn, so the rest of the hotel keeps trading. Tell us your quiet periods and access windows and we will plan around them.
Do you work in London buildings with loading restrictions?
Yes. Inductions, permits and timed loading are routine for us in London. Share the building’s contractor rules and we’ll work to them. All of Greater London is inside the ULEZ, and our planning allows for it
Can you take on work for an FM or managing agent?
Yes, and through main contractors too. We quote, schedule and report back in the way that suits your process, with a 12-month guarantee on the workmanship.
When can the area be used after sealing?
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.
Is failed sealant stripped out, or sealed over?
Every scrap of failed sealant is removed before the new bead goes on. A bead laid on old silicone peels away, so it isn’t something we do.
How long will the new sealant last?
There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.
Are your applicators CSCS-carded?
Yes. If you need card details for site access, tell us and we’ll confirm them with the quote.
Diagnose, treat, sign off
We begin with a short walk round with whoever looks after the building, agreeing which joints are in scope, where to start and what must stay open. 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 zones and timings are agreed with whoever manages the building. Phased work keeps the rest of the building in use.
- First, details reach us through the quote form or a site visit.
- The cause is diagnosed and the scope priced as a fixed quote.
- Where parts of the building must stay open, the work is phased.
- Old sealant is cut out completely, never sealed over.
- A suitable product for each joint goes in at the right depth and is tooled.
- A final walk-round, then the 12-month guarantee applies.
Getting the site ready
- Warn occupants and staff about the work
- Share your working hours and any access restrictions
- Have the specification and drawings to hand

Specifications, drawings and tender packages are welcome with any enquiry, and we will price against exactly what is specified. Smaller jobs need nothing more than photographs and a few notes.
