How we handle commercial sealant in Finsbury Park
Mr Mastic brings more than 20 years’ experience to commercial sites, and we are fully insured and ARBOMaster approved. If your site needs RAMS or insurance details, tell us, and we will confirm what we can supply with the quote. Common call-outs are for worktop sealant that has shrunk and stained and shower leaks reaching the floor below, on welfare facilities, rental portfolios and retail & leisure sites.
Across London, offices, shops, hotels, student halls and blocks of flats all need sealant work from time to time, from washroom silicone to fire-rated sealant around pipes and cables passing through walls. Out-of-hours working can be arranged where a building in Finsbury Park can’t close.
A one-year guarantee comes as standard, so you are covered after we’ve gone.

What the job involves on each surface
Welfare facilities
Welfare facilities, shower rooms and changing areas need to stay usable. We can plan the work in sections.
Rental portfolios
An empty property is easy to reseal, so the next tenant moves in to clean, sound joints.
For landlords and businesses
Landlords and agents in Finsbury Park can book us as well as householders. Sealant work between tenants is a simple way to keep a property in good order before the next move-in.
Whether it’s one flat or a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a 12-month guarantee.

Is parking an issue for commercial sealant in Finsbury Park?
Parking in Finsbury Park, as in most of London, takes a little planning: a visitor permit or a nearby bay makes the day run more smoothly.
Will it make a mess?
Tidy work is part of the job. We protect what’s around the joints, and the area is left clean when we finish.
Can you match the sealant colour?
Yes. Sealants come in white, clear, grey and other colours for many products, and we’ll agree it with you first.
What do you put in the joint?
It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.
Do you provide RAMS?
Tell us what your site asks contractors for. We’ll confirm what we can supply before work is booked.
Where is Mr Mastic based?
Our base is in Crawley, and we work across South East England, London and Scotland.
What should I tell you?

What we do, step by step
Most of a good job is in the preparation, and we do not rush it. Joints are cleaned back and dried before anything new goes in. In total, it usually takes as long as the scope needs, from one welfare room to a full building. For a job in Finsbury Park, parking and access are the things to plan: let us know about parking, the floor we will be working on and any lift or shared entrance.
- We agree a programme with you: which rooms, in what order, at what times.
- We go through your site’s paperwork needs, such as RAMS, before work begins.
- Old sealant is cut out room by room and joints cleaned and treated.
- We reseal with the right product for each joint.
- Each finished area is checked with you and given a cure time.
Before we arrive
- Mention if the joints have been sealed before
- Keep pets and children clear of the area while we work
- Move anything stored near the joints

Can I do it myself?
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
Aftercare tips
How long the joints last depends on use and care. Here’s what we suggest:
- Act on lifting sealant before it leaks
- Leave squeegees in busy showers
- Keep extractor fans working and serviced
- Check the joints during routine room inspections
Strong chemicals and scourers wear silicone out faster. Ask cleaners to use mild products and soft cloths on the sealant.
Planned resealing is easier to manage than emergency repairs. We can fit the work around bookings, shifts and opening hours, rather than closed at short notice.
What happens if it’s left?
Sealing over the old bead can seem the fastest option, but silicone doesn’t bond to silicone, so it lifts. Doing it properly once is less disruptive than doing it badly twice. In a London flat, a failed joint rarely stays your problem alone: water can reach the neighbours below, and gaps in fire-rated joints affect the whole building.
What you pay reflects the work, not a rough estimate. That’s why we ask a few questions first and give you a clear quote before work begins.
