What sealant work cannot fix
A few problems are outside what sealant work can do:
- Deciding who is responsible under a builder’s warranty
- Baths and trays that move too much for sealant to cope with
- Plumbing faults behind the sealant
If in doubt, ring 0345 464 0079 or drop us an email and we will say what we think.

Should I try it myself first?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
What new build mastic looks like in Edgware Bury
Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Many of London’s new homes are flats in bigger developments, where snags may need reporting through the developer or the managing agent.
If you’ve bought a new home near Elstree & Borehamwood station, the sealant around baths, showers and frames is worth checking in the first year or two.

The process
Once we’re on site, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. Most jobs then take anything from a few hours to several days, depending on the number of plots. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in Edgware Bury. A visitor permit or a nearby bay makes the visit run more smoothly.
- First we work through your snagging list or plot schedule with you.
- We cut out every bit of the failed or messy sealant.
- We clean off dust from the build and prime the surfaces where the product needs it.
- New sealant suited to each joint is applied and tooled neatly.
- Finally, each room is checked and you are given the cure time.
Getting ready for the visit
- Tell us about access, such as stairs, a lift or high-level joints
- Mention any parking rules near the property
- Move anything stored near the joints

Edgware Bury questions
Can parking be tricky for a visit in Edgware Bury?
London parking needs a little planning, so let us know about permits, bays or a driveway when you book. The visit is then planned around what’s available.
Do you work for landlords with property near Elstree & Borehamwood station?
Yes, rental work is part of what we do. Just phone 0345 464 0079 or send us an email and tell us about the property, and we’ll give you a clear quote.
Will it make a mess?
No. The area is protected while we work and cleaned up afterwards.

Yes, we do. Our applicators work in Edgware Bury, and the service is the same as everywhere else.
Are you an approved applicator?
Yes. Mr Mastic is an ARBOMaster approved applicator and we’re fully insured too.
Do you have insurance?
Yes. Full insurance covers our work, and we can confirm the details when we quote.
Can you work from my snagging list?
Yes. Send it with pictures and we will quote for the sealant items. Items that need a plumber, tiler or the builder are flagged.

Surface by surface
Bathrooms and en suites
New-build bathrooms and en suites are where sealant fails most often. We cut out the failed bead, clean and prime, and reseal with anti-fungal sanitary silicone.
Windows and doors
Draughts around new frames are often a sealant gap. We look at the joints and reseal where needed.
Why deal with it now?
Water getting past a failed seal in a new build reaches walls and floors that are still settling. Resealing promptly protects the new finishes around it. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and once it shows in Edgware Bury, the repair is bigger than a sealant job.
Doing several joints on one visit is generally more efficient than separate visits, so it’s worth mentioning everything you’d like done. We’ll give you a clear quote for the lot.
