New build mastic for homes and businesses in Shalden
Building dust is behind a lot of failed new-build sealant. Each joint is cleaned of dust and primed where the product calls for it, so the sealant actually sticks rather than sitting on a layer of grit. If you have joints pulling apart as timber shrinks and cracked caulk along new skirting, we can put it right, whatever the surface.
Work in a small place like Shalden just needs the journey and access planning, and once on site, the job is the same as anywhere.
A one-year guarantee comes with the work, just as it does everywhere we cover.

Signs you need new build mastic in Shalden
Later trades and the final clean can damage fresh sealant. A bead disturbed before it has cured may never seal properly and it shows once the home is in use.
Common reasons people contact us are:
- Joints pulling apart as timber shrinks
- Beads laid onto grit and dust from the build
- Skirting joints opening in the first winter
- Plot mastic for developers ahead of handover
If you’ve bought a new home near Alton station, the sealant around baths, showers and frames is worth checking in the first year or two.
Before booking anyone
- Which sealant they’ll use, and why
- Whether all the old sealant comes out first
- When the joint can take water or movement
- The length of the guarantee
Why it’s worth doing now in Shalden
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 Shalden, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.

Different surfaces, different methods
Show homes

What affects the cost of new build mastic
You will get a clear quote before we start. It’s based on:
- Mould in or behind the old joints
- How many areas need sealing
- When we can work, for business premises
- How much old sealant there is and how hard it is to remove
The cost reflects the work involved, not a rough estimate. That’s why we ask about the job first.
What we need to know
Before you ask for a quote, have a think about:
- How we’d reach the joints
- What the problem is, such as mould, gaps, leaks or cracking
- The type of property
- Any previous sealing or DIY work
The more we know about the job, the more useful the quote. Tell us where the job is, what’s wrong and how much there is, and email pictures if that’s easy.
What happens on the day
We bring everything the job needs with us, so you do not need to buy or prepare anything. After a quick look at the joints together, we protect the area and start. Most jobs take a few hours for most snagging lists, longer for a run of plots. Somewhere as small as Shalden, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- First we work through your snagging list or plot schedule with you.
- The old bead comes out in full, with no layer left behind.
- Surfaces are cleaned of building dust and primed where needed.
- A sealant chosen for each area goes in and is tooled smooth.
- Finally, each room is checked and you’re given the cure time.
Before we arrive
- Keep children and pets away from the work area
- Mention any sign-in or site rules at work premises
- Tell us about access, such as stairs, a lift or high-level joints

Where is Mr Mastic based?
We work from Crawley. We cover Shalden and the rest of Hampshire, along with the rest of our area.
Can you reseal over the builder’s sealant?
No. Over-sealing traps mould and water and soon fails. We remove every bit of the old bead before resealing.
Do you work for hotels and businesses?
Yes. Hotels, offices and other businesses use us.
Can I add another job to the visit?
Yes. Just list everything you need and you will get one quote.
Is there a guarantee?
Yes. Each job is guaranteed for twelve months, large or small.
Is it worth resealing while the house is still settling?
Any seal that’s leaking should be redone straight away. Cosmetic gaps can wait until the first year or two of movement has passed.
Can I do it myself?
If you’re set on DIY, put the effort into 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.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
