Sealant contractors in Fullwell Cross
We cover Fullwell Cross for sealant work for offices, hotels, washrooms and commercial buildings. Old material cut out, joints cleaned and sealed neatly and every job guaranteed for a year.
- Failed floor-level joints in accessible wet rooms
- Whole floors of tired en suites
- Leaks from showers into rooms or ceilings below
Why deal with it now?
Sealing over the old bead can seem the fastest option, but it will not bond, and it lifts again soon. Doing it properly once is less disruptive than doing it badly twice. Damp from a failed joint spreads quietly in older London brickwork and timber, and by the time it shows on a wall or ceiling in Fullwell Cross, the repair is bigger than the sealant job would have been.
Combining jobs into one visit is generally more efficient than separate visits, so tell us about everything that needs sealing. You will get one clear quote for the whole job.

Honest limits
Sealant isn’t the answer to every problem, and we’d rather say so up front. Sealant won’t put right:
- Cracked trays or baths rather than failed joints
- Leaking pipework, valves or wastes (a plumber’s job)
- Certifying fire stopping or building compliance
Not sure which it is? You can ring 07833 053749 or drop us an email and we will tell you honestly before booking.
Surfaces we seal
- Rental portfolios
- Office washrooms & kitchens
- Welfare facilities

- Hotel bathrooms
What we do, step by step
Before we leave, we go over the finished joints with you. The visit itself generally takes as long as the scope needs, from one welfare room to a full building, depending on how much there is to do. In Fullwell Cross, flats, stairs and shared entrances are part of the routine. Mention any building rules, key holders or managing agents when you book.
- The first visit is a look round the site to agree the scope.
- Working hours are agreed, including early starts or out-of-hours work where it can be arranged.
- Areas are protected and the failed sealant removed.
- Once dry, every joint is resealed and tooled.
- Housekeeping or site staff are told when each area can be used.
Getting ready for the visit
- Keep children and pets away from the work area
- Move anything stored near the joints
- Let us know about earlier repairs to the joints

A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints, and email photos if that is easy.

DIY sealant or a professional job?
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
Questions from Fullwell Cross
Can you do commercial sealant in Fullwell Cross?
Yes. We work across London and the South East, and Fullwell Cross is part of that. You can call 07833 053749 or drop us an email and let us know what needs doing.
Can parking be tricky for a visit in Fullwell Cross?
London parking needs a little planning, so let us know about permits, bays or a driveway when you book. That way the visit can be planned around it.
How long do rooms need to be out of use?
Most areas can be used after around 24 hours. We give a cure time for each area.
Is there any odour?
Some sealants have a smell while they cure. Opening a window helps.
What should I tell you?
The location, the problem and the rough size of the job. Photos by email help too.
Can new sealant go over the old?
No, it will not last. It can look neat for a few weeks, but the new bead soon lifts. Removing the old sealant completely is the only lasting way.
Do you hold any approvals?
Yes. Mr Mastic is an ARBOMaster approved applicator and we are fully insured too.
Do you remove the old sealant?
Yes. All of the old material is cut out and the joint cleaned before resealing.

How to look after the new joints
Once the sealant has cured, a few habits help it last:
- Keep a record of which rooms were resealed and when
- Book larger programmes for quieter times of year
- Keep strong chemicals and scourers off the joints
- Pass on the cure time to whoever cleans the rooms
Strong chemicals and scourers wear silicone out faster. A mild cleaner and a soft cloth is enough for the joints.
Black sealant in a staff washroom or guest bathroom draws complaints. The longer it’s left, the deeper it grows into the silicone, and only replacement fixes it.
For landlords and businesses
Mouldy or split sealant often shows up at the end of a tenancy. We can quote for more than one property at once.
Letting agents often deal with us directly. Send the address, what’s needed and the access arrangements and we will give you a quote.
