How we handle coloured sealant in Finchley
Natural materials vary across a single elevation: a stone or brick facade shifts in tone from one area to the next. We choose a colour that reads well across the surface rather than chasing one spot. If you have a bead that fights the cladding or frame colour and sealant that no longer suits recoated frames, we can help, on office fit-out finishes, cladding panels and hotel bathrooms and public areas alike. Searching for sealant specialists in Finchley? Mastic Doctor has worked for contractors, FMs and building owners since 2005, with CSCS-carded applicators.
Around Finchley, as across the capital, commercial buildings range from converted period premises to recent office and mixed-use blocks, which means one visit can cover joints against stone, brickwork, coated aluminium and shop-fit panels. Each surface gets its own preparation and, where it’s seen, a sealant colour that sits with it.
Guaranteed is the last step of every job. You get a 12-month guarantee on our workmanship, and the quote explains what it covers.

Doing it in-house
Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.
What happens if it’s left?
Across a chain of shops or hotels, consistency matters. Setting one product and colour for every site avoids variation across the programme. Getting scaffold, permits or access booked in Finchley takes effort, so while access is arranged it pays to renew all failing joints, not just the worst.
We don’t publish prices, because the scope varies so much from one building to the next. Call for a quote.
Why us?
- Specification-led, product-correct work
- One phone line for London, the South East and Scotland

How a job runs
Working in a building that stays open takes some planning. The work area is signed and kept contained, with routes through the building left open and work section by section so the rest of the building stays in use. Planning a London job such as one in Finchley starts with access: booked loading, goods lifts, the building’s permit system and a spot to keep materials. Send the building rules and access times with your enquiry.
- We confirm the joint type and the product it needs.
- Your RAL reference, sample or photo is checked against that product’s colours.
- The nearest colour is agreed, with a sample bead where needed.
- The existing bead comes out, then faces are cleaned and backed.
- We mask, seal and tool to a clean line.
- We remove the masking and walk the finished joints with you.
What we need from you
- Tell us your opening times and when work is allowed
- Send any specification or drawings in advance
- Agree which areas must stay open

Does your area include sites such as Finchley Industrial Centre, near Finchley?
Yes. We cover Finchley and the area around it, including industrial estates, business parks and retail parks such as Finchley Industrial Centre. A few photographs and the unit address let us price the work.

Yes. Tell us the product and colour reference and we will confirm availability for a quick quote. We plan around trading hours where we can, within our working week.
How long does a job like this take?
It depends on the scope, but the work normally takes a few hours or a phased programme, depending on joint lengths and how many colours are involved. Larger or phased jobs take longer, and we will give you a timescale with the quote.

Which sealant will you use?
If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
What Finchley’s businesses ask us to seal
Most London commercial buildings run contractors through a reception, a permit system and booked goods-lift slots. We work within them, one zone at a time. A 2-mile radius around Finchley takes in a good number of hotels. A hotel refurbishment is full of joints that guests will see, and a matched colour keeps them discreet, with rooms done in turn while the rest stay let.
Occupiers with premises at both Finchley Industrial Centre and Friern Bridge Retail Park could have the sealant at each handled under one quote. For premises near New Southgate station, which lies north-east of Finchley, footfall is part of the plan: work is phased so shops and offices keep trading. Industrial estates such as Finchley Industrial Centre, 1.3 miles north of Finchley, have offices, trade counters and welfare areas whose sealant ages like any other building’s.

Looking after the joints
Problems stay small when the joints are checked regularly. In particular:
- Keep harsh solvents away from visible joints
- Reseal whole runs rather than patching single joints
- Settle the colour with the designer at the start
- Approve a sample bead on high-profile areas
Give the sealant its full cure time before cleaning or handling the area. Fresh coloured beads show fingerprints and dust more easily, so keep the area clear.
Use one product and colour reference across a building or brand. It keeps repairs and new sites consistent.
