Questions from Colindale
Do you work for hotels and guest houses in Colindale?
Yes, we work for hotels as well as homes and businesses. Rooms can be done a few at a time, so the building stays open.
Can parking be tricky for a visit in Colindale?
In much of London, parking needs planning: a visitor permit or a nearby bay makes the day run more smoothly.
What sealant do you use?
Quality sealants from brands including Arbo and Everbuild, chosen to suit the joint. We’ll tell you what we are using and why.
Should I try DIY first?
That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.
How do I get a quote for commercial sealant in Colindale?
The cost depends on the size of the job, access and how much old sealant has to come out. Call for a quick quote and we’ll talk you through it.
Can I add another job to the visit?
Yes. More than one area can go on one quote.
Can you match the sealant colour?
We will suggest a colour to suit the surroundings, from white and clear to greys and other shades. The product needed can limit the range.
Is there any odour?
It depends on the product. Some smell for a while, some hardly at all.

When something else is needed
We’d rather tell you now than do work that won’t last, so here’s what sealant can’t put right:
- Extraction that is not working, which needs an electrician or ventilation contractor
- Water coming from plumbing rather than sealant
- Water damage behind the tiles that needs a tiler or builder
Not sure which it is? You can call 0345 464 0079 or email us and we’ll tell you honestly before booking.
What we seal

What we do, step by step
A visit follows a simple pattern: we look at the joints together, protect the area around them, do the work and clear up. It generally takes a few hours per room, so whole buildings are phased. In Colindale, flats, stairs and shared entrances are part of the routine. Mention any building rules, key holders or managing agents when you book.
- Tell us the rooms, hours and site rules, and we will plan the programme.
- 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.
- Rooms are handed back in order, each with its cure time.
Before we arrive
- For indoor joints, keep the area dry beforehand if you can
- Tell us about access, such as stairs, a lift or high-level joints
- Keep pets and children clear of the area while we work

Advice
How the job changes by surface
Retail & leisure sites
Shops, gyms, leisure centres and restaurants all have joints that need sealing. We can plan around opening hours.
Office washrooms & kitchens
Long vanity tops have joints that hold water and grime. We renew it in one tidy, continuous bead.
Common problems we fix in Colindale
Heavy use means more movement: different weights, constant use and daily cleaning. A tray that is not fully supported soon tears its seal.
The most common problems we see are:
- Shower leaks reaching the floor below
- Mouldy bathrooms flagged at a tenancy check
- Split sealant where wet room floors meet walls
- Split sealant around staff kitchen worktops and sinks
Community buildings like St Matthias the Apostle church are part of the picture too: its kitchen and washroom sealant needs looking after like anywhere else.
What your quote should include

- What preparation is included
Looking after it afterwards
Good habits help new joints last longer. Our tips:
- Pass on the cure time to whoever cleans the rooms
- Get split or lifting joints looked at early
- Add sealant to your planned maintenance checks
- Log resealing so you know what’s due
Keep the extraction running and maintained. In internal bathrooms, a weak or broken fan lets moisture linger, and that’s what keeps mould away.
Watch for the warning signs: black spots in the silicone, corners lifting, staining on the ceiling below or a musty smell. Any of these means the joints need attention.
