Our commercial sealant contractors service in W2
Sealant joints are easy to overlook until one lets water in. Mastic Doctor works as a commercial sealant contractor for facilities managers, managing agents and main contractors looking after property in W2. We find out why the sealant joints failed, take them out and seal again using a sealant that suits the joint. We work on external facade joints, floor and threshold joints and movement joints in walls and floors, and the usual reasons a site gets in touch are frame sealant that has cracked, shrunk or pulled away and smeared sealant across finishes from a rushed job.
Diagnose, treat, 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.
- First, details come to us: photographs, drawings or a schedule of the areas.
- Next comes a diagnosis and a fixed quote.
- Before anything is cut out, we agree access, timings and sequence.
- We strip the failed bead and prepare both faces of the joint.
- We fit backing to the right depth, prime where specified and lay the new bead.
- We walk the completed areas with you and sign them off under the 12-month guarantee.
What affects the price in W2
Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you’ll have a fixed figure to work with.

Commercial premises across W2
The commercial stock in W2 mixes older town-centre buildings with newer offices and units, in places such as City of Westminster, Paddington Green and Paddington and beyond. Each building needs the right product for its surfaces, from stone and brick to coated aluminium and laminate.
Around the motorway corridors of the South East, business parks and industrial estates are common, and W2 is part of the area we cover.
City of Westminster: For a hotel such as Beaumont Hotel (under half a mile south of City of Westminster), the colour of a joint at the bar or the bath matters to the look of the room. For a retailer at a site such as Brompton Cross District Shopping Centre., 1.5 miles to the south-west of City of Westminster, the joints clients see are as much part of the fit-out as the shelving.
Leave it or put it right?
Putting off a reseal normally moves the cost rather than avoiding it. Once water gets behind the seal, finishes and ceilings underneath are next, and the bill then involves other trades. Resealing while only the sealant has failed keeps the job small.

When to bring in a specialist
Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.
Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
Owners, agents and contractors
Whether you are a managing agent, a property factor or an owner’s representative: send details, get a fixed quote, we seal, guaranteed. We can agree access arrangements and keyholder contacts beforehand.
Blocks and communal areas make up much of the work for housing associations and agents. Work can be phased so residents and staff keep access throughout, and each stage is agreed with your contact.
Honest limits
Before quoting, we check that sealant is the right answer. It isn’t the answer for:
- A failed roof covering or waterproofing membrane
- Structural cracks or movement the joints weren’t designed for
- Leaks from pipework, wastes or valves (that’s plumbing)
Cost factors for sealant joints
These are the things that shape the price:
- Backing rod, priming and other preparation
- How accessible the joints are
- Distance, for remote addresses
- Specialist products, such as fire-rated or hygienic sealants
Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.

W2: questions and answers
What site paperwork can you provide?
Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote. We’re CHAS accredited and a Constructionline member, with five million pounds of public liability insurance.
When can the area be used after sealing?
That comes down to the sealant and the temperature. Some products skin over quickly but need longer to cure fully, so we will confirm the curing time on the day.
How do you choose the sealant?
A specification, where there is one, decides it. Without one, the joint decides: its movement, its surfaces and what it has to cope with.
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.
Is your work guaranteed?
Our workmanship on each job is backed by a 12-month guarantee. We’re fully insured for public liability as well.
