For managing agents and facilities managers
For main contractors, we work as the sealant subcontractor, on new build and refurbishment alike. Programme, specification and site rules come first, and our applicators hold CSCS cards.
Building owners and managing agents use us on everything from one building to a spread of sites. Several sites can go on one quote, which keeps the paperwork simple.
Coloured sealant in Kensal Green, done properly
Natural materials vary across a single elevation: a stone or brick facade shifts in tone from one area to the next. We choose a colour that reads well across the surface rather than chasing one spot. If you have poorly tooled joints on visible finishes and colour changes after a rebrand or refit, we can help. Searching for sealant specialists in Kensal Green? Mastic Doctor has worked for contractors, FMs and building owners since 2005, with CSCS-carded applicators.
Buildings in a London area such as Kensal Green rarely close for maintenance: offices with staff at their desks, shops trading below flats and receptions that can’t be roped off for long. Work is split into zones agreed with the building or facilities manager, so the premises keep working around us, and where a brand finish matters, the sealant colour is agreed first.
We stand by our work: 12 months, guaranteed. That covers our preparation and application, and we come back if anything isn’t right.

From enquiry to sign-off
Inspect, seal, sign off: every visit follows that pattern. First comes an inspection and agreement on scope, then we prepare and seal each joint with the specified product, and the job ends with a walk round and sign-off. All of Greater London is in the ULEZ, and kerbside space in Kensal Green can be scarce. If there’s a loading bay, a car park or a permit we can use, tell us when you send details.
- Photos or drawings show us the finishes and joints.
- Colour options from the specified product’s range are shared with you.
- Tell us your site hours and access windows and we will plan around them.
- We prepare each joint, prime where needed and fit backing.
- The agreed colour is installed and tooled neatly.

What happens if it’s left?
A mismatched or discoloured bead is a small detail that buyers, guests and clients notice, especially in shop fits and hotels. Resealing in a suitable colour is a modest cost against the finishes it sits beside, and it lifts the whole area. Repeat call-outs disrupt occupied London buildings, so a proper job first time, with the old sealant fully removed, is worth it.
Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.

Coloured sealant around Kensal Green: how the place shapes the job
London premises usually come with a building manager, booked loading and house rules for contractors. Our planning starts from those rules rather than working round them later. A 2-mile radius around Kensal Green takes in a good number of hotels. In hotels, sealant shows everywhere, from bathroom joints to reception counters, so colour and a clean finish matter, with rooms done in turn while the rest stay let.
Premises within reach of Kensal Green station, less than half a mile east of Kensal Green, often have busy frontages where joints are seen by everyone passing. If you have premises on more than one site, say at Mitre Bridge Industrial Estate and Cumberland Business Park, one contractor and one quote can cover both. Units at places like O2 Centre (to the north-east of Kensal Green) are refitted as brands change, and the joints have to suit each new scheme.

FAQs: Kensal Green
Must a hotel around Kensal Green close while you work?
In most cases no closure is needed: we work room by room or floor by floor. Housekeeping and our team agree each day’s rooms.
Do you cover business parks and estates near Kensal Green, such as Mitre Bridge Industrial Estate?
Yes. Estates, retail parks and business parks around Kensal Green, Mitre Bridge Industrial Estate among them, are all within reach. Photos and a short description are enough for a first look.
Can you guarantee a perfect colour match?
No, not in every case. We choose the nearest standard colour and can agree a sample bead first.
How many days will you need on site?
The duration is planned around your programme and the access we’re given. You will have an expected duration with the quote.
Is it fine to apply new sealant on top of old?
No, never. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.
Can you fit around our working hours?
Give us your site hours and any access windows in your enquiry, and we’ll plan around them. Our office runs Monday to Friday, 8am until 5pm.
Do you match sealant to RAL colours?
Yes. We compare the RAL reference with the colours made for the specified sealant. You will see the nearest options.

Should maintenance staff do it?
Some joints are best left to specialists: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.
There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.
What affects the price in Kensal Green
Sealant work doesn’t have a standard rate, since sites vary so much. What we look at:
- The site’s rules and procedures
- Backing rod, priming and other preparation
- Removal of failed or old sealant
- How much there is to seal
A quote for colour-matched joints depends on how many there are, their condition and the access, plus any specification you’re working to. Ask us for a fixed quote.
Before you send an enquiry
To price the job accurately, we need a clear picture of the site. Useful things to include:
- Rough lengths or quantities, or drawings if you have them
- When you need the work done
- A wide shot and a close-up of the area
- Where the site is, with the postcode
We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To start the process, give us a call on 01277 525 020 or email a schedule or drawings.
Different surfaces, different methods
Powder-coated and anodised frames
Metallic and anodised finishes are hard to match exactly with sealant. We’ll suggest the nearest standard colours so you can choose.
Natural stone
Stone has variation, so the aim is a colour that sits naturally against it. A stone-safe neutral-cure product is used.
