About our new build mastic in Howe Green
Some owners wait for the first year’s movement before having joints redone. That makes sense for small gaps that are just cosmetic, but a seal that is letting water through needs doing now. We work on kitchens, show homes and windows & doors, and common reasons people get in touch are sealant applied over dusty or wet surfaces and messy sealant that spoils new finishes.
Work in a small place like Howe Green just needs the journey and access planning, and the work itself is the same as on any site.
We guarantee the work for a year. If something isn’t right with it in that time, tell us and we’ll put it right.

What affects the quote in Howe Green
We do not publish a price list. What we look at:
- The size of the job
- Whether old sealant or filler has to be cut out
- Which sealant suits the joint
- Whether the work is at height
Doing several joints on one visit is normally more efficient than separate visits. We will send you a clear quote for the lot.
Asking for a quote
Photos by email are helpful but not essential. Please mention:
- Whether it’s a home or a business
- Whether it has been sealed before
- Roughly how big the job is
- A few photos by email, if you can
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints.
Aftercare tips
How long the joints last depends on use and care. We suggest:
- Put sealant faults on your snagging list early
- Look at the sealant regularly in the first couple of years
- Wait for the cure time before using a resealed shower
- Open a window or run the fan after bathing
Follow the cure time we give you before the area gets wet. Silicone is normally left for about a day.
A seal that splits early is often a sign of movement. Have it resealed, and the tray or bath checked, before it gets worse.
Howe Green questions
Will you come out to Howe Green?
Yes, Howe Green is covered. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Do you work for landlords with property near Chelmsford station?
Yes, rental work is part of what we do. Just ring 0345 464 0079 or send us an email and tell us about the property, and we will give you a clear quote.
Will it make a mess?
Tidy work is part of the job. Nearby surfaces are protected, and we clear up when we’re done.
Should I try DIY first?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.
Can you work from my snagging list?
Yes. Snagging lists are a common starting point for us. We agree the sealant items with you before work begins.
Can you match the sealant colour to my new kitchen or bathroom?
Most bathroom joints are white or clear, but sealant comes in other colours too. We match the colour to the finish before we begin.
Where is Mr Mastic based?
Mr Mastic is based in Crawley. We cover Howe Green and the rest of Essex, along with the rest of our area.
Do you remove the old sealant?
Yes. Sealing over old sealant is the main reason resealing fails early, so we never do it.
What new build mastic looks like in Howe Green
Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
In and around Howe Green, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint. For new homes near Chelmsford station, it’s worth checking the sealant early, while snags are still fresh.

Leave it or put it right?
For developers, getting the sealant right first time saves return visits. Snagging visits for failed sealant cost time on every plot, and they’re avoidable with good preparation. Where a wall is exposed, as many are in small places like Howe Green, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
We don’t show prices on the website, because each job is priced on what it involves. Call for a quick quote.

Should I try it myself first?
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.
What we cannot put right
We will always be straight with you, so here’s what new sealant won’t do:
- A tray or bath that isn’t properly supported, until it’s fixed
- Structural cracks in walls or ceilings
- Cracked trays, tiles or worktops
If you’re not sure, just call 0345 464 0079 or email us and we’ll give you a straight answer.
