About commercial sealant contractors in N18
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 N18. We find out why the sealant joints failed, take them out and seal again using a sealant that suits the joint. We work on floor and threshold joints, kitchen worktops and splashbacks and window and door perimeters, and the failures we are asked to look at most are wall and floor joints that have lost their seal and weathered facade sealant that no longer flexes.
We follow your site rules from the start: sign-in, induction and whatever permit system the building uses. Once we’re cleared to begin, the joints are worked through in the order agreed with your site contact, and each area is checked before we leave it.
- We begin with whatever information you have, whether that’s photos, a drawing or a list of locations.
- 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.
- Backing and primer go in where needed, then the chosen sealant is applied and tooled.
- We walk the completed areas with you and sign them off under the 12-month guarantee.
What you will pay

Near you in Upper Edmonton
In Upper Edmonton, that means premises near Pymmes Park, St Mary's Church and No.8 Tottenham pub, among other places. You will also find London Academy of Excellence Tottenham (0.6 miles south), Tottenham University Technical College (0.6 miles south) and St John and St James CofE Primary School (less than half a mile south). There’s a railway station in Upper Edmonton itself: Silver Street station. Other landmarks nearby include North Middlesex University Hospital (less than half a mile west) and Broomfield House Museum (2.2 miles west). Not far away are Pole Hill and Highams Park Lake.
Shops, offices and hotels in N18
From Edmonton, Tottenham and Upper Edmonton outwards, N18 has a broad spread of commercial premises: shops, offices, hotels, restaurants and units. We cover the whole area, so occupiers with several sites can use one contractor and one point of contact, with colours matched site to site where the brand needs it.
All of Greater London is inside the ULEZ, and much of the South East is within easy reach of the capital, so jobs in N18 are planned with access, loading and parking in mind.
Upper Edmonton: For premises near Silver Street station (under half a mile north-west of Upper Edmonton), footfall is part of the plan: work is phased so shops and offices keep trading. A business with units at Compass West Industrial Estate and Edmonton Green Shopping Centre needn’t use two contractors for its sealant.
Aftercare for building managers
Sealant joints are maintenance items, and how long they last depends on how they’re treated. Our advice:
- Ask cleaners to use a soft cloth and mild cleaner on sealant
- Log reseals in the O&M or maintenance records
- Report cracked or peeling sealant early
- Check joints after other trades have worked nearby
We stand behind the workmanship with a 12-month guarantee. File the handover note with the building records, and tell us if a joint we sealed gives trouble within that time.
Movement joints that fill with debris stop working. With nothing soft to close against, the materials either side take the load and start to break up. At that point it’s a repair job rather than a reseal.
Signs you need commercial sealant contractors
Every sealant joint is a maintenance item. How long one lasts depends on the movement it takes, its exposure to sun and weather, the cleaning regime, the traffic and the product itself. In commercial buildings those factors tend to act together.
Typical triggers for a call:
- Untidy joints in a reception, shop floor or lobby
- Window and door perimeter joints that have cracked open
- Sanitary sealant that has gone black and patchy
- Movement joints packed with grit and debris
Different surfaces, different methods
Washrooms and toilets
Washroom joints take water, cleaning chemicals and constant use. We cut out mouldy or split beads and reseal in anti-mould sanitary silicone.
Shop fronts and retail fit-outs
Retail work normally has to fit around trading. Tell us your trading hours and access windows and we’ll plan around them, working in sections where that helps.
What sets the cost
What shapes the price:
- Induction, permit and paperwork requirements
- Access and working height
- How much existing material needs removing
- Working within restricted access windows
The specified product makes a difference, and so does the preparation, from cutting out to priming and backing rod. Access, phasing and site requirements come into it too.
Sending details for a quote
The more we know, the firmer the quote. Helpful details to send:
- The product your specification calls for
- The site address and postcode
- Whether the building will be occupied during the work
- A wide shot and a close-up of the area
To get a fixed quote, ring 01277 525 020 or email a schedule or drawings, telling us the site location and the nature of the job. Our quote form is another easy route.
Work for main contractors and building owners
When you manage a building on behalf of an owner, you need clear quotes and clear reporting. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative, plus a 12-month guarantee.
Agents, factors and owners’ representatives all follow the same route: send details, get a fixed quote, we seal, guaranteed. We can agree access arrangements and keyholder contacts beforehand.
Questions about N18
Is it OK to apply fresh sealant over existing beads?
The old bead is stripped out first. Then the joint is cleaned, primed where the maker specifies, backed to depth and resealed.
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, with a 12-month guarantee on the workmanship.
Do you cover N18?
Yes. We take on work across N18.
Can areas stay open during the work?
It’s mostly about sequence: we agree access windows, phase the work and keep enough facilities open. Tell us what has to stay open and we’ll plan the job around it.
What about asbestos in old mastic?
It’s possible in older buildings, especially those built before 2000. Before cutting anything out, we ask for the asbestos register or survey, and if something is suspected, work stops until it’s tested.
When is resealing likely to be due?
It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.
What guarantee do you give on resealing?
Our workmanship on each job is backed by a 12-month guarantee. We are fully insured for public liability as well.
