New build mastic in Chase Cross
Failed shower seals, gaps along the skirting and messy beads are common items on a new-home snagging list. If you are still within the builder’s snagging or warranty period, tell them first. We work on windows & doors, show homes and bathrooms & en suites, and the jobs we see most are sealant applied over dusty or wet surfaces and cracked caulk along new skirting. Whether you are looking for a mastic company, a sealant applicator or a sealant contractor in Chase Cross, Mr Mastic can help.
New flats are going up across London, many of them in larger developments. In a new development, snags are often reported through the developer or the managing agent, and shower seals that fail early, skirting joints that open up and gaps at thresholds are all common snags.
A one-year guarantee comes as standard, so you’re not left on your own once the job is done.

DIY sealant or a professional job?
If you’ve already had a go yourself, that’s fine. We cut it out and start again, so just mention it when you contact us.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.

Signs you need new build mastic in Chase Cross
Later trades and the final clean can damage fresh sealant. A bead disturbed before it has cured may never seal properly, and the problem shows up after you move in.
Look out for any of the following:
- Leaking shower tray seals in a new home
- Untidy sealant flagged on a snagging list
- Plot mastic for developers ahead of handover
- Cracked sealant around new window and door frames
If you’ve bought a new home near Gidea Park station, the sealant around baths, showers and frames is worth checking in the first year or two.

Chase Cross: your questions answered
Do you work for landlords with property near Gidea Park station?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. You can phone 07833 053749 or email us with the details for a clear quote.
Is Chase Cross in your area for new build mastic?
Yes, Chase Cross is within the area we cover. Our work covers London and the South East. You can call 07833 053749 or email us and tell us what needs doing, and we will send you a clear quote.
Do I have to be there?
We need access to the joints, so we’ll agree that with you when we book. Indoors, that normally means someone at home.
Can you quote for more than one area?
Yes, and it often makes sense. Combining jobs makes good use of the visit, so mention them when you ask for a quote.
Do you take on second-fix sealing for builders?
Yes. Second-fix sealing in bathrooms, kitchens, frames and floors is part of what we do. We clean and prime joints properly to keep callbacks down.
Will there be a smell?
There can be a smell while the sealant cures, but it fades. Ventilation helps.
What colour sealant will you use?
That depends on what the joint meets: white or clear in most bathrooms, and a colour to suit worktops, frames and floors elsewhere. We agree the colour before we start.
Is it normal for sealant to crack in a new home?
New homes dry out and move in their first couple of years, and sealant is often applied quickly onto dusty surfaces. Either can make it fail early.
Landlords, agents and businesses in Chase Cross
We regularly work with letting and managing agents. Send the address, what’s needed and the access arrangements and we’ll quote.
Failed sealant is one of the commonest items on a check-out report. We can quote for more than one property at once.
Leave it or put it right?
The builder is generally the first port of call while the snagging or warranty period runs. If it keeps failing or is not dealt with, we can reseal it properly. In London conversions, one flat’s bathroom is often above another flat’s ceiling, so a small leak from tired sealant can mean a neighbour’s ceiling and a lot of disruption. Dealing with it early is far simpler.
Combining jobs into one visit is generally more efficient than separate visits, so tell us about everything that needs sealing. We will give you a clear quote for the lot.
What you get with us
- Quality sealants from Arbo and Everbuild
- Domestic, commercial and hotel work
- White, clear, grey or another colour, product permitting
