About our coloured sealant in Acton
We take on colour-matched work across new fit-outs, refurbishments and resealing of existing joints on sites in Acton. On resealing, matching the existing colour is often as important as the seal itself. The enquiries we see most involve dirty, discoloured joints in public areas and colour changes after a rebrand or refit, on hotel bathrooms and public areas, natural stone and brick and office fit-out finishes. Looking for mastic applicators who cover Acton? Mastic Doctor has worked for contractors, FMs and building owners since 2005, with CSCS-carded applicators.
Around Acton, as across the capital, commercial buildings range from converted period premises to recent office and mixed-use blocks, 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.
We sign every job off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

Why act early in Acton
A standard colour is quicker to source, though not always right. Where joints are on show, choosing a better colour is typically worth it at handover. Repeat call-outs disrupt occupied London buildings, so cutting the old sealant out fully and doing it right once is the better route.
The product called for affects the cost, as does the preparation each joint needs, from cutting out to priming and backing rod. Access, phasing and site rules also count.
Why appoint us
- Workmanship guaranteed for 12 months
- Old sealant cut out, never sealed over
- Sealing commercial buildings since 2005
- CSCS-carded applicators

For managing agents and facilities managers
Main contractors use us as their sealant subcontractor, on new build and refurbishment alike. We work to your programme, your specification and your site rules, and our applicators hold CSCS cards.
Planned maintenance programmes are welcome: resealing failed joints building by building, on a schedule that suits your budget. Acton can form part of a wider programme across Greater London.
On site: what to expect
On arrival, we report to your site contact and complete whatever induction the building runs. Everything around the joints gets protected before anything is cut or cleaned, with the work itself usually taking about the same time as any other sealant work, plus a little longer if a sample bead is agreed first. For a job in Acton, access comes first. Send the building rules and access times with your enquiry.
- We start with photographs, drawings or a visit to see the finishes.
- We send the closest colours from the product’s range.
- Tell us your site hours and access windows and we will plan around them.
- Joints are prepared, primed where specified and backed.
- The agreed colour is installed and tooled neatly.
Before we start on site
- Have the specification and drawings to hand
- Agree which areas must stay open
- Point out parking and an unloading spot
Getting a fixed quote

Questions about Acton
Can you work at a site such as Victoria Industrial Estate, by Acton?
Yes. Our area takes in Acton and its surroundings, with estates and business parks such as Victoria Industrial Estate included. A few photographs and the unit address let us price the work.
Does a hotel in Acton need to shut while its sealant is renewed?
In the majority of cases no closure is needed: we work room by room or floor by floor. We agree the order of rooms and the timings with you before we start.
When is resealing likely to be due?
Nobody can honestly give a figure in years, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular inspection is the best way to catch problems early.
What if there’s asbestos in the old mastic?
Asbestos is possible in some older mastics, particularly in buildings from before 2000. We check the asbestos register before cutting out old sealant in an older building, and if asbestos is suspected, work stops until it’s tested. We don’t remove asbestos-containing materials.
Will sunlight affect the sealant colour?
Some change over time is normal. Exposure, product and colour all play a part, so no colour stays exactly the same for ever.
Can you follow the specification on our project?
Yes. The specification and the manufacturer’s installation guidance are what we work to.
Are you CHAS accredited and on Constructionline?
Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.
What affects the price in Acton
A fixed quote reflects the actual work. It takes account of:
- Joint width, depth and condition
- Travel to remote or island sites
- Whether the work must be split into stages
- How accessible the joints are
Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.
What we need to price the job
There’s no need for a formal survey. A few details are enough to get going:
- The postcode of the building
- Anything awkward about access or site hours
- Clear photographs of the problem areas
- The product your specification calls for
Send details, get a quote, we seal, guaranteed: that’s how every job runs. The first step is to call 01277 525 020 or email us with what you know.
Doing it in-house
What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.
General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class.
Surface by surface
Powder-coated and anodised frames
Metallic and anodised finishes are hard to match exactly with sealant. We will suggest the nearest standard colours so you can choose.
Shop-fit and joinery finishes
Retail fit-outs mix many finishes in a small space. Each joint gets a colour that suits the materials it sits between from the product’s range.
Frontages, fit-outs and joints in Acton
Acton has a good number of hotels close by, all within 2 miles. Hotel refurbishments are where a matched sealant colour earns its place: bathroom, bar and reception joints have to sit with the finishes, and the work can be phased so the rest of the hotel keeps trading. The 3 miles around Acton take in at least three named trading estates, business parks or retail parks. Sites like these see regular refits, with shopfronts, offices and staff areas to seal.
In hotels such as Blue Star Hotel, less than half a mile to the west of Acton, refurbishments usually mean bathroom, bar and reception joints where a matched sealant colour has to sit with the finishes. On estates like Victoria Industrial Estate, 0.8 miles north-east of Acton, the office and welfare end of each unit has its own sealant to maintain. A business with units at Victoria Industrial Estate and Westpoint Trading Estate needn’t use two contractors for its sealant.
