Having a single contact for all your sites makes sealant far simpler to manage.

To get a programme moving in Paddington Green, ring 01277 525 020 or email the details over with the site addresses. Most enquiries involve black mould through washroom sealant that won’t clean off and smeared sealant across finishes from a rushed job, on movement joints in walls and floors, window and door perimeters and floor and threshold joints. Searching for sealant specialists in Paddington Green? Mastic Doctor has worked for contractors, FMs and building owners since 2005.
We price commercial jobs in Paddington Green from photos, drawings or a site visit, with the scope listed so everyone knows what’s included.
Much of the planning for a London commercial job is about getting in and out: loading bay slots, goods lifts, permits to work and somewhere to keep materials. Once that’s settled, the sealant joints are resealed in sections so tenants are disturbed as little as possible.
What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Cost factors for sealant joints
What shapes the price:
- The size and state of each joint
- Induction, permit and paperwork requirements
- Phasing around occupants
- How much there is to seal
The product called for affects the cost, and so does the preparation, such as cutting out, priming or new backing rod. Access, phasing and site rules also count.
Before you send an enquiry
Diagnosis starts before we arrive. Tell us:
- When you need the work done
- How the joints are reached, and at what height
- Where the site is, with the postcode
- Whether the building will be occupied during the work
Send details, get a quote, we seal, guaranteed: that’s how every job runs. To take the first step, call 01277 525 020 or email a schedule or drawings.
Common questions from Paddington Green clients
Can you work in a London building with booked loading and goods-lift slots?
Yes. Inductions, permits and timed loading are routine for us in London. The building manager’s rules go straight into our method. The ULEZ covers the whole of Greater London, which we allow for
Does a hotel in Paddington Green need to shut while its sealant is renewed?
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’ll plan around them.
Does commercial sealant work come with a guarantee?
Our workmanship is guaranteed for 12 months. We’re fully insured for public liability as well.
Do you work for facilities managers and managing agents?
Yes. You send the details, we return a fixed quote, and the job is done and signed off.
When is resealing likely to be due?
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 you CHAS accredited and on Constructionline?
Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.
How do you choose the sealant?
A specification, where there is one, decides it. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
Different surfaces, different methods
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.
Window and door perimeters
Inside, cracked sealant around frames and window boards is common. The product depends on whether the joint will be painted, in a shade that suits the frame.

Working on commercial sites near Paddington Green
Most London commercial buildings run contractors through a reception, a permit system and booked goods-lift slots. We plan around them and agree phasing so tenants and customers aren’t disrupted. A 2-mile radius around Paddington Green takes in plenty of hotels. Refits in hotels bring joints at vanity tops, bar counters and reception desks where the colour has to suit the scheme; work is planned so the hotel keeps trading.
Units at places like Kensington Arcade (1.5 miles south-west of Paddington Green) are refitted as brands change, and the joints have to suit each new scheme. A hotel such as Maitrise Hotel, under half a mile to the east of Paddington Green, shows how much sealant a hospitality building has on show, from bathroom joints to the bar. For premises near London Paddington station, less than half a mile to the south of Paddington Green, footfall is part of the plan: work is phased so shops and offices keep trading.

On site: what to expect
When we get to site, we report to your site contact and complete whatever induction the building runs. Everything around the joints gets protected before any cutting starts, with the work itself normally taking anything from part of a day on a short run of joints to several weeks on a large phased package. In Paddington Green, most buildings stay in use during the work, so zones and timings are agreed with whoever manages the building. Areas are handed back as each section is finished.
- We start with the evidence: photos, drawings or a look on site.
- You get a fixed quote covering removal, preparation and the new sealant.
- Sequence, access and working times are settled before the first joint is touched.
- Each joint is stripped, cleaned back to sound faces and primed where the maker specifies.
- Backing goes in, the new sealant is laid and tooled, and the area is left neat.
- Completed areas are signed off with you under our 12-month guarantee.
What we need from you
- Tell us your opening times and when work is allowed
- Warn occupants and staff about the work
- Share the asbestos register for older buildings

Why it’s worth doing now in Paddington Green
Reactive resealing, a leak at a time, tends to cost more overall than a plan. Planning the work across a year or a portfolio means fewer separate visits and a predictable spend. We will suggest an order, worst sealant joints first. Access in London is hard enough to arrange once, so it makes sense to deal with every failing joint while access is in place.
Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits.
Why us?
- Fully insured, including public liability cover
- Specification-led, product-correct work
- Colours confirmed for the specified product
- 12-month guarantee on workmanship

What sealant work can’t fix
Not every problem is a sealant problem, and we’re upfront when that’s the case. These need a different solution:
- Broken glass or blown double-glazed units
- Water from a services leak rather than a joint
- Suspect materials that need testing and specialist removal
Not sure which it is? You can phone 01277 525 020 or send details through our quote form and we will tell you honestly before you book.
Surfaces we seal
- Kitchen worktops and splashbacks
- Window and door perimeters
- Washrooms and tea points
- Floor and threshold joints
- Movement joints in walls and floors
- External facade joints
Aftercare for building managers
To get the most from the new sealant:
- Act on the first lifting edges rather than waiting
- Make sure contractors see the asbestos survey before cutting out old mastic
- Keep abrasive pads and scrapers off resealed joints
- Note dates and locations of sealant work for future planning
Our workmanship on each job is backed by a 12-month guarantee. File the handover note with the building records so it’s easy to find if a joint we sealed gives trouble inside the 12 months.
An open joint in a food area or toilet collects dirt and moisture that cleaning can’t reach. Environmental health officers look at how cleanable surfaces are, which makes sound joints worth keeping on top of.
