Commercial sealant contractors in Kensal Rise
Some sealants used before 2000 can contain asbestos, so older stock needs a check first. We ask to see the asbestos register or survey before old sealant is disturbed, since managing asbestos is the dutyholder’s responsibility. Anything suspect is left alone until it has been tested. We work on window and door perimeters, movement joints in walls and floors and kitchen worktops and splashbacks, and the usual reasons a site gets in touch are untidy joints in a reception, shop floor or lobby and shrunken sealant along kitchen worktops and splashbacks. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Kensal Rise is the same: the right product in a properly prepared joint.
In Kensal Rise, as anywhere, the first joints to go are usually the ones that work hardest: frame perimeters in the sun, floor joints at doorways and anything that gets wet every day.
Around Kensal Rise, as across the capital, commercial buildings range from converted period premises to recent office and mixed-use blocks, 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.
A 12-month guarantee applies to all our work in Greater London. Should something we installed fail, call the office on 01277 525 020 or email drawings and photos and we’ll come back to it.

Leave it or put it right?
Some low prices are low because nothing gets cut out. New sealant laid on old silicone has nothing to bond to, so it peels. Our prices always include removal of the failed bead and full joint preparation. Access in London is hard enough to arrange once, so it makes sense to deal with every failing joint while access is in place.
The price depends on how many linear metres there are, what has to come out first and the access. Call for a quote when you are ready.

Doing it in-house
For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.
Diagnose, treat, sign off
The first thing on site is a walk round with your contact, to confirm the scope, the order of work and any areas we must keep clear. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. For a job in Kensal Rise, access comes first. Give us the hours we can be on site and we’ll schedule to suit.
- 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.
- Each joint gets a suitable sealant, laid to depth and tooled.
- We check the work with you, and the 12-month guarantee starts.
Getting the site ready
- Send asbestos survey details if the building is pre-2000
- Point out parking and an unloading spot
- Let us know about inductions and permits

Advice
Questions we’re asked in Kensal Rise
Can you cope with the access rules in a London building?
Yes, most London buildings have access rules of some kind, and we plan around them. Share the building’s contractor rules and we will work to them.
Is The Quadrant Business Centre, near Kensal Rise, within your area?

When can the area be used after sealing?
We’ll confirm how long the chosen product needs to cure.
Are you CHAS accredited?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member, which helps with supplier vetting.
How long does a job like this take?
That varies with the scale of the job, though a typical visit normally takes a few hours for one area, or a planned series of visits across a bigger building. For bigger or phased jobs, we will set out a timescale with the quote.
Can you handle sealant work across several sites?
Yes, within the areas we cover: South East England, Greater London and Scotland. Each site gets the same process and a single contact.
Can you take on work for an FM or managing agent?
Yes. A large share of our work comes through facilities managers, managing agents and landlords as well as contractors. We can work to your instruction process and site rules.
What the job involves on each surface
Shop fronts and retail fit-outs
Most shops can’t close for a reseal. Tell us your trading hours and access windows and we will plan around them, working in sections where that helps.
Commercial kitchens and tea points
A smooth, continuous joint is easier to keep clean, and cleanability is part of what an inspector looks at. We seal to a neat, cleanable finish and work around service times you agree with us.
What sets the cost
A fixed quote reflects the actual work. It allows for:
- Backing rod, priming and other preparation
- Distance, for remote addresses
- Specialist products, such as fire-rated or hygienic sealants
- Whether the work must be split into stages
The product called for affects the cost, as does the preparation each joint needs. Access, phasing and site rules also count.
What to include in your enquiry
Diagnosis starts before we arrive. Let us know:
- Whether the building will be occupied during the work
- Your programme or deadline
- Any specification or named product
- Asbestos survey details if the building is older
A good quote starts with a clear picture: what’s there, how much of it, how we reach it and what’s specified. Send what you have, and we will arrange a site visit if anything is unclear.
Working on commercial sites near Kensal Rise
Contractor rules in London buildings can be strict, with inductions, permits and timed loading all normal. We fit into those systems and phase the work so the building keeps operating. A 2-mile radius around Kensal Rise takes in a good number of hotels. Hotel refurbishments are where a matched sealant colour earns its place: bathroom, bar and reception joints have to sit with the finishes, with rooms done in turn while the rest stay let.
Premises within reach of Kensal Rise station (under half a mile north-west of Kensal Rise) often have busy frontages where joints are seen by everyone passing.

A business with units at The Quadrant Business Centre and Mitre Bridge Industrial Estate needn’t use two contractors for its sealant.
