How we handle new build mastic in Bull Hill
New homes move as they dry out. Timber shrinks, plaster dries and baths and trays bed down, so sealant that was laid quickly before handover often cracks. We work on windows & doors, kitchens and plot handovers, and people most often call us about gaps between new skirting and floors and untidy sealant flagged on a snagging list.
In a village or hamlet like Bull Hill, 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.
Your job is guaranteed for a year, as with all our work.

What we’re called out for in Bull Hill
A new house holds a lot of water from the build, which takes a year or two to dry out. As it does, timber shrinks and joints open, and sealant that cannot keep up splits.
The problems people usually mention when they call are:
- New-build shower sealant that has already split
- Joints pulling apart as timber shrinks
- Sealant work across a run of new homes
- Cracked caulk along new skirting
For new homes near Lymington Town station, it’s worth checking the sealant early, while snags are still fresh.
Questions to ask before you book
- When the joint can take water or movement
- What insurance they hold
- Is VAT in the price?
- What happens if the job turns out different
Joints and finishes in Bull Hill homes
Bull Hill is close to the coast. New homes near the sea put their outside mastic to work from day one, so it’s worth checking at snagging. Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
In and around Bull Hill, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

Aftercare tips
After the cure time, these simple habits help:
- Get a leaking seal dealt with right away
- Raise failed sealant with the developer while you are covered
- Watch for new gaps as the house dries out
- Use the extractor fan every time you shower
Clean the sealant with a mild detergent and a soft cloth. Keep scourers and harsh chemicals off it as they wear the bead.
A seal that splits early is often a sign of movement. Getting it resealed properly, and any movement checked, stops it recurring.
What we can’t put right
Some problems need a builder, plumber or other trade rather than us:
- Cracked trays, tiles or worktops
- Cracking that points to a structural problem
- Your warranty claim itself, which is between you and the builder
Not sure which it is? You can call 0345 464 0079 or drop us an email and we’ll tell you honestly.

Can I do it myself?
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
How we quote for new build mastic
The quote reflects the job in front of us. We take into account:
- The number of rooms or windows
- Whether old sealant or filler has to be cut out
- How easy the joints are to reach
- Any working-time requirements on site
No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all play a part.
Asking for a quote
You do not need to know the technical terms. Just tell us:
- How we’d reach the joints
- Photos by email, if that is easy
- Whether it’s a home or a business
- Roughly how big the job is
For new build mastic in Bull Hill, call 0345 464 0079 or email us. A short description of the job and where it is helps us quote, and we will agree the price before any work begins.
The process
Once we are on site, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. Most jobs then take a few hours for most snagging lists, longer for a run of plots. Somewhere as small as Bull Hill, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- Each joint is checked for movement before work begins.
- We remove the failed sealant and clean the joints.
- Joints are dried and primed where the product calls for it.
- New sealant goes in, with baths filled first so they’re at their heaviest.
- The finished joints are checked and the cure times given.
Before we arrive
- Clear items away from the joints we are working on
- Mention any sign-in or site rules at work premises
- Tell us about any previous sealing or DIY attempts

Advice
Your questions about new build mastic in Bull Hill
Is Bull Hill in your area for new build mastic?
Yes. We work across London and the South East, and Bull Hill is part of that. You can phone 0345 464 0079 or email us and let us know what needs doing, and we will send you a clear quote.
Can you help a landlord with a rental near Lymington Town station?
Yes. We work for landlords and agents as well as homeowners. You can call 0345 464 0079 or send us an email with the details for a clear quote.
Will you just run a new bead over the existing one?
No. New silicone won’t bond to old silicone, so it soon lifts and traps water. The old sealant always comes out first.
Is the work guaranteed?
Yes, for a year. If anything is not right with the work within the year, let us know and we will sort it.
How long does new build mastic take?
That depends on how much there is to do, but most jobs take a few hours in a single home. We will tell you when we quote.
Should I go to my builder first?
Your builder, if you’re still in their snagging or warranty period. After that, or if their repair keeps failing, we can do it.
Where is Mr Mastic based?
We’re a Crawley-based firm. Our area covers South East England, London and Scotland.
Will it make a mess?
Very little: the area around the joints is protected first, and we tidy up before we go.
Surface by surface
Plot handovers
Good preparation at handover saves snagging later. Dust from the build is removed first.
Bathrooms and en suites
Trays and baths in new builds settle as they’re used. The joint is stripped back before the new bead goes in.
