What new build mastic looks like in Woodlands
London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
For new homes near Ashurst New Forest station, it’s worth checking the sealant early, while snags are still fresh.

New build mastic in Woodlands, done properly
Building dust is behind a lot of failed new-build sealant. We clean every joint thoroughly and prime where the surface and product need it, so the sealant actually sticks. If you are dealing with cracked caulk along new skirting and joints pulling apart as timber shrinks, we can put it right, on plot handovers, bathrooms & en suites and kitchens alike.
In a village or hamlet like Woodlands, new homes are more likely to be a barn conversion or a handful of houses than a big estate. Each still needs its sealant and floor joints finished properly.
Big or small, you get the same 12-month guarantee in Woodlands and across Hampshire.

Woodlands: your questions answered
Is Woodlands in your area for new build mastic?
Yes, Woodlands is within the area we cover. Our work covers London and the South East. Just phone 0345 464 0079 or drop us an email with a few details of the job, and we will give you a clear price.
I let a flat near Ashurst New Forest station. Can you help?
Yes. We work for landlords and letting agents as well as homeowners, and several properties can be quoted together. You can phone 0345 464 0079 or send us an email with the details for a clear quote.
Will the old sealant be removed?
Always. Sealing over old sealant is the main reason resealing fails early, so we never do it.

Do you have insurance?
Yes. Mr Mastic is fully insured, and we’ve been doing sealant work for more than 20 years.
Can you work from my snagging list?
Yes. Send it with photos and we’ll quote for the sealant items. Items that need a plumber, tiler or the builder are flagged.
Will there be a smell?
Sometimes, a little. Any smell clears as the sealant cures.
Can you do plot mastic on a new development?
Yes. We work through plots to your schedule, room by room. Get in touch with the number of plots and the scope for a clear quote.
Signs you need new build mastic in Woodlands
On many sites, sealant goes on in the final rush before handover. Joints are not always cleaned of dust or primed, so the bead never bonds properly.
Look out for these signs:
- Untidy sealant flagged on a snagging list
- Beads laid onto grit and dust from the build
- Kitchen sealant that has pulled off the wall
- Plot mastic for developers ahead of handover
In and around Woodlands, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

How the job changes by surface
Kitchens
Worktops in new homes can move slightly as the house dries, opening gaps behind the upstand. A fresh flexible bead closes them.
Bathrooms and en suites
Baths, showers, basins and trays in new bathrooms are the most common new-build reseal. We cut out the failed bead, clean and prime, and reseal with anti-fungal sanitary silicone.
When something else is needed
New sealant can’t fix everything, and we’d rather say so up front. Sealant won’t put right:
- A tray or bath that isn’t properly supported, until it’s fixed
- Damaged fittings that need replacing
- Structural cracks in walls or ceilings
If you’re not sure, just phone 0345 464 0079 or email us and we will give you a straight answer before booking.

How it works
Good joint work is mostly preparation, and we don’t rush it. Joints are cleaned back and dried before anything new goes in. In total, it normally takes a few hours in a single home. Somewhere as small as Woodlands, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We go through the snagging list or plot schedule and agree the joints to do.
- Failed or untidy sealant is cut out completely.
- Each joint is cleaned of dust and grit, then primed if required.
- New sealant suited to each joint is applied and tooled neatly.
- We check every joint and tell you how long each needs to cure.
How to prepare
- For business premises, tell us about site rules or sign-in
- Tell us about access, such as stairs, a lift or high-level joints
- Try not to wet indoor joints just before the visit

Advice
Keeping the joints in good condition
A little care helps the new joints last. We recommend:
- Put sealant faults on your snagging list early
- Resist patching a failed seal with a tube from the DIY shop
- Don’t wait for the house to settle if water is getting through
- Ventilate bathrooms well, especially in the first year
Follow the cure time we give you before the area gets wet. Silicone is generally left for about a day.
Lifting sealant traps moisture and mould behind it. Dealing with it before it goes black keeps the job straightforward.

DIY sealant or a professional job?
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.
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. Everything old must be removed first.
How we quote for new build mastic
The price is agreed before any work begins. It takes into account:
- How many rooms, windows or areas are involved
- Whether the work is at height
- The old material and how stubborn it is
- The product the joint needs
Doing several joints on one visit usually makes better use of the time than several visits, so tell us about everything that needs sealing. We’ll give you a clear quote for the lot.
What we need to know
Photos help, but a description is a good start. Try to tell us:
- Where the job is, and your postcode
- Any previous sealing or DIY work
- What’s wrong with the joints now
- The rough size of the job
It all starts with a short chat. Tell us what’s wrong, where it is and how much there is. When it suits you, ring 0345 464 0079 or email us.
