New-build mastic & snagging in Howlett End, Essex
New build mastic across Howlett End and nearby, with every bit of old sealant taken out first and a 12-month guarantee.
- Shower seals failing in the first year or two
- Gaps behind new kitchen upstands
- Second-fix sealing on new plots
Different surfaces, different methods
Kitchens
Worktop, upstand and sink joints in new kitchens often get a hurried bead. We remove it and reseal with a kitchen-suitable sealant.
Skirting and floors
New homes often develop a gap between skirting and floor. A flexible sealant closes it without cracking like caulk.
New build mastic in Howlett End, done properly
A new build should have a neat, sound bead at every joint. When the finish is smeared, patchy or already cracking, it’s worth putting right early, before water gets into the floor or walls. If you are dealing with skirting joints opening in the first winter and cracked sealant around new window and door frames, we can help, on plot handovers, skirting & floors and kitchens alike.
In a village or hamlet like Howlett End, new homes are more likely to be a barn conversion or a handful of houses than a big estate. Every one needs its sealant and floor joints done properly, whatever the size of the site.
We stand behind the work with a one-year guarantee.

Yes, smaller places are covered as well as towns. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Do you cover Howlett End for new build mastic?
Yes. Our work covers London and the South East, and Howlett End is part of that. You can ring 0345 464 0079 or drop us an email and tell us what needs doing.
Is the work guaranteed?
Yes. Every job comes with our 12-month guarantee.
Why has my new-build shower seal failed already?
There are normally two causes: the house moving as it dries, and sealant that never bonded properly. A proper reseal deals with both.
Should I wait before resealing?
It depends on whether water is getting through. Failed seals in wet areas need doing now, but cosmetic gaps can wait for movement to slow.
Will you just run a new bead over the existing one?
No. New silicone will not bond to old silicone, so sealing over the top fails quickly. We cut the old bead out completely.
Who should fix failed sealant in a new build?
If you are still within the builder’s snagging or warranty period, report it to them first. If they’re slow or the fix does not last, we can help.
Where is Mr Mastic based?
We are a Crawley-based firm. Our area covers South East England, London and Scotland.
Should I try it myself first?
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
What we can’t put right
We will not take on work that will not last, so here’s what sealant can’t put right:
- Baths and trays that move too much for sealant to cope with
- Settlement cracks that need a surveyor
- Damaged fittings that need replacing
If in doubt, phone 0345 464 0079 or send us an email and we will say what we think before you book.

What affects the cost of new build mastic
We do not publish a price list, because jobs vary so much. The quote depends on:
- The old material and how stubborn it is
- The number of rooms or windows
- Whether the work is at height
- The product the joint needs
Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. You’ll know the price before we begin.
What we need to know
Before you ask for a quote, have a think about:
- Access, such as stairs, a lift or height
- If it’s domestic, commercial or a hotel
- Photos by email, if that’s easy
- What the problem is, such as mould, gaps, leaks or cracking
Every job is quoted individually, so start by telling us what you need. Just call 0345 464 0079 or drop us an email with the details, and pictures are welcome.
Why deal with it now?
For developers, getting the sealant right first time saves return visits. Snagging visits for failed sealant cost time on every plot. Where a wall is exposed, as many are in small places like Howlett End, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
There are no prices on our website, because the cost depends so much on the job itself. Call for a quick quote.

- Every job guaranteed for a year
