Commercial sealant contractors for Clare Market sites
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
Aftercare for building managers
Regular inspection catches problems early. Specifically:
- Put external and wet-area joints on a regular inspection round
- On pre-2000 buildings, share the asbestos information before work starts
- Ask cleaners to use a soft cloth and mild cleaner on sealant
- Report cracked or peeling sealant early
Our workmanship on each job is backed by a 12-month guarantee. Keep the handover details with your O&M or maintenance records.
A failed external joint lets water in every time it rains. It can run into cavities, insulation and internal finishes long before anyone sees a stain. Resealing early keeps the problem in the sealant and out of the building.
Commercial mastic work in Clare Market
Sealant joints are easy to overlook until one lets water in, and in an occupied building failure normally announces itself as a stained ceiling or an unhappy tenant. Mastic Doctor works as a commercial sealant contractor for facilities managers, managing agents and main contractors looking after property in Clare Market. Our job is to diagnose the failure, remove the old bead and seal again using a product chosen for the movement and exposure. The enquiries we see most involve messy, uneven beads from earlier work that let the building down and sanitary sealant that has gone black and patchy, across external facade joints, washrooms and tea points and movement joints in walls and floors. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Clare Market, that means joint design, primers and backing rod as standard.
On a typical commercial building in Clare Market, the joints that fail first are the hardest-worked ones: south-facing perimeters, entrance thresholds and busy washrooms.
Buildings in a London area such as Clare Market rarely close for maintenance: offices with staff at their desks, shops trading below flats and receptions that can’t be roped off for long. We plan the joints floor by floor or unit by unit with the building manager, so areas stay in use.
We sign every job off with a 12-month guarantee. The promise is simple: if our work fails within that year, we put it right.

Your questions answered
Do you take on jobs in Clare Market where loading and access are tightly controlled?
Yes. Inductions, permits and timed loading are routine for us in London. Share the building’s contractor rules and we’ll work to them.
Will our hotel in Clare Market need to close for the work?
Rarely. Rooms or floors are done in turn, so the rest of the hotel keeps trading. Housekeeping and our team agree each day’s rooms.
How soon can the area be used again?
We’ll confirm how long the chosen product needs to cure, and flag anything to keep off until it has cured.
Do you work directly for building managers?
Yes. Use our quote form to send the site details, or phone or email us.
Do you work to architects’ specifications?
Yes. We follow the specification, along with the manufacturer’s installation guidance, and any queries are raised before we start.
Which sealant will you use?
A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
What about asbestos in old mastic?
It can, on some older buildings. That’s why we ask for the asbestos information first, and stop if a material is suspect until it’s tested. HSE guidance on asbestos is a useful reference.
For managing agents and facilities managers
Whether you’re a managing agent, a property factor or an owner’s representative: send details, get a fixed quote, we seal, guaranteed. Keys, access and contacts can be agreed in advance.

Working on commercial sites near Clare Market
In London, commercial buildings often have managed loading bays, goods lifts and permit-to-work systems. We fit into those systems and phase the work so the building keeps operating. Clare Market has at least three named business or industrial parks inside a 3-mile radius. Tenant changes on such sites bring fit-outs, and fit-outs bring new joints.
Offices and shops close to stations such as London Charing Cross station, 0.6 miles to the south-west of Clare Market, tend to be busy all day, so sealant work is planned around opening hours. On estates like Grand Vitesse Industrial Estate, 1 mile to the south-east of Clare Market, the office and welfare end of each unit has its own sealant to maintain. Shopping centres and retail parks such as Brunswick Centre (0.7 miles north-west of Clare Market) see a steady turnover of shop fits, each leaving joints where colour and finish matter.
Clare Market is about 1 mile south of St Pancras, in Greater London. We send applicators to Clare Market for sealant joints. Our Greater London coverage takes in 764 places, from busy centres to rural villages.
If you need commercial sealant contractors in WC2H, W1D and WC2B, the process matches everywhere else we work: send details, get a quote, we seal, guaranteed. For a building on Drury Lane, New Square and Old Square or nearby, send details and we will quote for sealant joints.

Site staff or a sealant specialist?
General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.
Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.
On site: what to expect
Where the site stays busy, the work is phased so only one area is out of use at a time. Each section is protected, cleaned back and sealed, then reopened once the sealant allows before the next one starts. Most London premises stay occupied while we are on site, so we agree zones and timings with the building or facilities manager. Phased work keeps the rest of the building in use.
- Site photographs, drawings or a visit tell us what’s there and how it has failed.
- A fixed quote follows, with removal and preparation included.
- 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.
Getting the site ready
- Move anything stored against the joints
- Flag any permit to work we will need
- Tell us which areas need to stay in use

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’ll plan around them, phasing areas so the shop floor stays usable.
Movement joints in walls and floors
A trafficked floor joint needs a different product from a wall joint. The choice comes down to how much the joint moves and what runs over it.
Why deal with it now?
A failed seal around a window, worktop or panel doesn’t mean the element itself has to go. Often the fitting is sound and the joint is the only thing letting it down. A careful reseal is a far smaller undertaking than replacement. In a London building, a failed joint rarely affects only one party. Putting it right early is less disruptive than dealing with the consequences.
Whether it’s a single area or a whole estate, the same things set the price: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote and we will put a fixed figure on it.
