Why it’s worth doing now in Feltham
A brand roll-out or multi-site fit-out benefits from a consistent sealant colour. Fixing the colour reference at the start keeps every site the same from one fit-out to the next. Repeat call-outs disrupt occupied London buildings, so cutting the old sealant out fully and doing it right once is the better route.
The specified product makes a difference, as does the preparation each joint needs, from cutting out to priming and backing rod. Access, phasing and site requirements come into it too.

Coloured sealant in Feltham
Architects, designers and brand teams often specify the sealant colour as carefully as the finishes around it. Standard sealant ranges cover many colours, so we check what the specified product is made in at quote stage. We don’t promise an exact custom match, but we’ll show you the closest options. We work on office fit-out finishes, powder-coated and anodised frames and shop-fit joinery and counters, and the failures we’re asked to look at most are previous reseals that don’t match the original and white or grey sealant that clashes with the finish. A single leaking joint is often how a building in Feltham first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Much of the planning for a London commercial job is about getting in and out: booked loading, goods-lift times, the permit system and a place to stage materials. With access agreed, we work through the colour-matched joints a section at a time, keeping disruption to tenants low.
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.

What sealant work can’t fix
We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:
- Repairing damaged frames or cladding
- Colour variation across natural stone or brick that no single shade can match
- Custom-mixed sealant colours
If you are not sure, just speak to us on 01277 525 020 or email the details over and we will give you a straight answer before you book.
Surfaces we seal
- Hotel bathrooms and public areas
- Office fit-out finishes

- Shop-fit joinery and counters
- Cladding panels
- Powder-coated and anodised frames
Work for main contractors and building owners
FMs need a contractor who is easy to get on site. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we will confirm them with the quote.
As a CHAS accredited contractor and Constructionline member, we’re straightforward to vet for your supplier list. Our insurance certificate can be sent along with the quote.
Our process
Inspect, seal, sign off: that’s the shape of every visit. First comes an inspection and agreement on scope, then the work is carried out to the specified product and detail, and we finish with a walk round so the work can be signed off. All of Greater London is in the ULEZ, and kerbside space in Feltham can be scarce. If there’s a loading bay, a car park or a permit we can use, tell us when you send details.
- We confirm the joint type and the product it needs.
- Your RAL reference, sample or photo is checked against that product’s colours.
- The nearest colour is agreed, with a sample bead where needed.
- The existing bead comes out, then faces are cleaned and backed.
- Edges are masked and the coloured sealant applied and tooled.
- Masking comes off and the work is checked with you.
Preparing the site
- Move anything stored against the joints
- Explain the parking and delivery arrangements
- Send any specification or drawings in advance

Advice
Working on commercial sites near Feltham
Contractor rules in London buildings can be strict, with inductions, permits and timed loading all normal. We work within them, one zone at a time. A good number of hotels sit less than 2 miles from Feltham. In hotels, sealant shows everywhere, from bathroom joints to reception counters, so colour and a clean finish matter.
If you run a unit on an estate such as Maple Industrial Estate (0.5 miles south of Feltham), the trade counter, offices and staff facilities have joints to look after as well as the warehouse. If you have premises on more than one site, say at Maple Industrial Estate and Felthambrook Industrial Estate, one contractor and one quote can cover both. Shops and cafés around stations like Feltham station, less than half a mile to the east of Feltham, trade from early, so work is timed around them.
Feltham is about 6 miles south-west of Ealing, in Greater London. Anywhere in TW14, it works the same way: send details, get a fixed quote, we seal, and the work is guaranteed. 764 places across Greater London fall within our area, Feltham among them. London is covered too, around 14 miles from Feltham.

Aftercare for building managers
Your facilities or cleaning team can help the joints last. Pass these on to them:
- Reseal whole runs rather than patching single joints
- Brief cleaners about newly sealed joints
- Use one colour standard across multi-site work
- Put the colour reference on the finishes schedule
Include coloured sealant in planned building checks. Look for splits, lifting edges and staining.
Standardise the sealant colour on multi-site work. Consistency makes future work simpler and easier to manage.
Doing it in-house
Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and we will confirm the paperwork you need with the quote.
Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong normally costs more in the end than doing them right.
What else we do in Feltham
Questions we’re asked in Feltham
Does a hotel in Feltham need to shut while its sealant is renewed?
Rarely. Rooms or floors are done in turn, so the rest of the hotel keeps trading. We agree the order of rooms and the timings with you before we start.
Do you take on jobs in Feltham where loading and access are tightly controlled?
Yes, we plan every London job around the building’s own access rules. Send the building rules and access times with your enquiry. All of Greater London is inside the ULEZ, and our planning allows for it
Can coloured sealant be used in washrooms and kitchens?
Yes, where the product range allows. Coloured sanitary sealant suits tiled and stone wet areas in commercial interiors.
Does the colour affect how the joint performs?
The colour doesn’t change what kind of sealant it is. A properly prepared and tooled joint performs as the product intends.
Do you take on colour-matched sealant for shop fits and multi-site roll-outs?
Yes. We work with shop fitters, hotel groups and office fit-out contractors. Our area takes in Greater London, the South East and Scotland, so a consistent colour can run across several sites.
Can staff carry on working while you’re here?
Usually, yes. We phase the work so most of the building stays in use.
What do you charge?
It depends on the job: quantities, access, the product and any phasing. Call for a quote.
