New build mastic in Avisford, done properly
Dust is the enemy of new-build sealant. We clean every joint thoroughly and prime where the surface and product need it, so the new bead bonds properly instead of bonding to the dust. We work on windows & doors, plot handovers and show homes, and the jobs we see most are cracked sealant around new window and door frames and smeared, uneven beads picked up at snagging.
For a small place like Avisford, the journey and access are planned in advance, and the work itself is the same as on any site.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

When it is not the sealant
New sealant can’t fix everything, and we’d rather say so up front. It won’t solve:
- Cracking that points to a structural problem
- A tray or bath that isn’t properly supported, until it’s fixed
- Deciding who is responsible under a builder’s warranty

Leave it or put it right?
Running a new bead over the builder’s sealant might look tidy for a few weeks, but it won’t bond to the old layer. Taking it all out and starting again is the only way to get a lasting seal. Around Avisford, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Instead of a standard rate, we look at what your job involves: how many joints, what’s in them now and how we reach them. You’ll know the price before we begin.

How it works
There’s no need to move everything out, only the area right around the joints. Everything nearby is protected, and the job takes a few hours for most snagging lists, longer for a run of plots for a typical job. For a village or hamlet like Avisford, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- Each joint is checked for movement before any work starts.
- We remove the failed sealant and clean the joints.
- We make sure the joints are dry and prime them if needed.
- Baths are filled with water, then the new sealant is applied.
- The finished joints are checked and the cure times given.
How to prepare
- Tell us about access, such as stairs, a lift or high-level joints
- Mention any sign-in or site rules at work premises
- Tell us about any previous sealing or DIY attempts

Where is Mr Mastic based?
Mr Mastic is based in Crawley. Our applicators cover Avisford, along with the rest of our area.
Do you take out the old sealant first?
Yes, every time. New sealant won’t bond properly to old, so the joint is cleaned back first.
Should I wait before resealing?
If the seal has failed and water is getting in, do it now. Hairline cosmetic gaps can wait until the house has settled.
Are you insured?
Yes. We are fully insured.
Should I go to my builder first?
While the snagging or warranty period runs, the builder should be your first contact. If they’re slow or the fix doesn’t last, we can help.
Will you leave a mess?
We keep the work tidy. We protect what’s around the joints, and we clear up when we’re done.
Common problems we fix in Avisford
On many sites, sealant goes on in the final rush before handover. Joints aren’t always cleaned of dust or primed, so the bead never bonds properly.
The most common problems we see are:
- Gaps between new skirting and floors
- Smeared, uneven beads picked up at snagging
- Second-fix sealing on new plots
- Cracked sealant around new window and door frames
In and around Avisford, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

Different surfaces, different methods
Plot handovers
Developers can send the plot schedule and specification and we will quote. We seal bathrooms, kitchens, frames and floors to the agreed spec.
Windows and doors
A draught at a new window can be a missed or failed joint. We check and reseal the frame edges.
Looking after it afterwards
How long the joints last depends on use and care. We suggest:
- Don’t seal over failed sealant yourself
- Check bath and shower seals every few months as the house settles
- Wait for the cure time before using a resealed shower
- Don’t wait for the house to settle if water is getting through
Don’t stand on the bath edge or the lip of the tray in the first few weeks. Report any movement in a bath or tray.
A seal that splits early is often a sign of movement. Getting it resealed properly, and any movement checked, stops it recurring.
