Commercial sealant contractors across N22: what to expect
Mastic Doctor has been sealing joints for businesses and contractors since 2005: we are CHAS accredited and a Constructionline member, our applicators hold CSCS cards, and we carry five million pounds of public liability insurance. Let us know which site documents you need and they’ll be confirmed with the quote. We work on movement joints in walls and floors, external facade joints and window and door perimeters, and what we’re called in for most is sanitary sealant that has gone black and patchy and external beads that have gone brittle and cracked.
We bring the products specified for the job, along with primers and backing rod. Any old material is cut back to clean, sound faces, primer goes on where the manufacturer specifies it, and the sealant is tooled off neatly.
- Send details through our quote form, or ask for a site visit.
- We diagnose the cause of failure and price a fixed scope.
- Work is phased around your occupiers where areas need to stay in use.
- Old sealant is cut out completely, never sealed over.
- A suitable product for each joint goes in at the right depth and is tooled.
- We check the work with you, and the 12-month guarantee starts.
How we quote
What a job costs comes down to how many linear metres there are, how much old material needs removing and how the joints are reached. Call for a quote when you’re ready.

Where commercial joints are in N22
Commercial buildings across N22 range from older premises altered many times to recent units on business parks. Each building needs the right product for its surfaces, from stone and brick to coated aluminium and laminate.
The South East has large numbers of business parks and industrial estates, especially around the motorway corridors, and N22 is part of the area we cover.
Noel Park: Units at places like The Mall Wood Green (less than half a mile south-west of Noel Park) are refitted as brands change, and the joints have to suit each new scheme. For a hotel such as White Lodge Hotel, which lies south-west of Noel Park, the colour of a joint at the bar or the bath matters to the look of the room.
Keeping the joints sound
To get the most from the new sealant:
- Keep washroom and kitchen extraction working
- Note dates and locations of sealant work for future planning
- Respect the cure time before reopening an area
- Ask cleaners to use a soft cloth and mild cleaner on sealant
Brief your cleaning team on the joints that have been resealed. Abrasive pads, scrapers and some strong chemicals damage sealant surfaces; a mild cleaner is all most joints need.
An open joint in a food area or toilet collects dirt and moisture that cleaning can’t reach. Cleanability is something environmental health officers pay attention to.
When it isn’t the sealant
Honesty saves time and money. Fresh joints won’t solve:
- Leaks from pipework, wastes or valves (that’s plumbing)
- Cracking that needs a structural engineer to look at it
- A failed roof covering or waterproofing membrane
What happens if it’s left?
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 can help you prioritise, starting with the joints most likely to let water in.

Signs you need commercial sealant contractors
A good share of the joints we inspect were topped up instead of being renewed. New silicone has nothing to key into, so the top layer lifts, holds water and hides what’s going on. By the time it shows, there can be two or three layers to cut out.
What tends to prompt an enquiry:
- Shrunken sealant along kitchen worktops and splashbacks
- Weathered facade sealant that no longer flexes
- A top-up bead over failed sealant, now lifting
- Untidy joints in a reception, shop floor or lobby
Should maintenance staff do it?
Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
FAQs: N22
How long does a job like this take?
We plan the time on site around your programme and access. We’ll give you an estimate of time on site when we quote.
How long before the joints can be used?
We will confirm how long the chosen product needs to cure, and flag anything to keep off until it has cured.
Are your applicators CSCS-carded?
Yes. We use CSCS-carded applicators.
Do you cover N22?
Yes. We cover N22, within our coverage of Greater London, South East England and Scotland. For a quote, speak to us on 01277 525 020 or email us.
Can weather delay the job?
For external joints, yes. The joint has to be dry and within the product’s temperature range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.
How do you choose the sealant?
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.
Can you follow the specification on our project?
Yes. We follow the specification, along with the manufacturer’s installation guidance, and any queries are raised before we start.
