About our new build mastic in New Alresford
We carry out plot mastic and second-fix sealing for builders, and snagging reseals for new-home owners. In both, preparation makes the difference since hurried prep is behind a lot of new-build failures. Typical jobs include gaps behind new kitchen upstands and plot mastic for developers ahead of handover, on kitchens, show homes and bathrooms & en suites.
For a new home in or near New Alresford, it’s worth checking the sealant early. Gaps at skirtings, shower seals pulling away and missing mastic around frames are common snags.
Each job carries a 12-month guarantee.

What affects the quote in New Alresford
The price is agreed before any work begins. It’s based on:
- How easy the joints are to reach
- How much there is to do
- When we can work, for business premises
- How much old sealant there is and how hard it is to remove
Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.
What we need to know
Photos by email are helpful but not essential. Please mention:
- A few pictures by email, if you can
- Any access issues, like height or stairs
- Any previous sealing or DIY work
- The type of property
Asking for a quote is easy: let us know the job and the location. Photos by email help us understand the job.
How it works
At the end, we look at the finished work together. The visit itself usually takes a few hours in a single home, depending on the size of the job. Parking around New Alresford is usually easier than in a town centre, but mention any lanes, gates or long drives. For outside work, side access and the height of the joints help us plan.
- We look at why each joint failed, including any movement.
- Old sealant is cut out and the joints cleaned.
- 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.
Preparing for the visit
- Mention if the joints have been sealed before
- For business premises, tell us about site rules or sign-in
- For indoor joints, keep the area dry beforehand if you can
Getting a quote
The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints, and email photos if that’s easy.
Advice
Do you need new build mastic in New Alresford?
Fresh sealant can be knocked or cut by trades finishing off. If it’s disturbed before curing, the joint can be left weak and it shows once the home is in use.
Common reasons people contact us include:
- Beads laid onto grit and dust from the build
- Worktop and upstand sealant coming away
- Second-fix sealing on new plots
- Cracked caulk along new skirting
Whether the job is in New Alresford itself or nearby, the right material for each joint matters as much as a neat finish.
What your quote should include
- Whether the sealant suits the joint
- Whether they’re fully insured
- What happens if the job turns out different
- What guarantee comes with the work
Looking after it afterwards
No joint lasts for ever, but care makes a real difference. Our tips:
- Look at the sealant regularly in the first couple of years
- Follow the cure time we give you
- Record problems with dated pictures
- Report sealant problems to your builder during the snagging period
Photograph failed sealant before it’s redone and keep the builder’s replies. It helps if anything else comes up during the warranty period.
Don’t let the snagging period run out with sealant problems unreported. Once it ends, the repair may be down to you, so raise it early.
Surface by surface
Kitchens
Worktops in new homes can move slightly as the house dries, which opens gaps along the back. A fresh flexible bead closes them.
Bathrooms and en suites
New-build bathrooms and en suites are where sealant fails most often. The old sealant comes out and anti-fungal sanitary silicone goes in after cleaning and priming.
Can I do it myself?
If you’ve already had a go yourself, that’s fine. We cut it out and start again, so tell us about it when you ask for a quote.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
When it isn’t the sealant
In fairness, there are a few things sealant will not fix:
- Deciding who is responsible under a builder’s warranty
- Cracked trays, tiles or worktops
- Structural cracks in walls or ceilings
If in doubt, ring 0345 464 0079 or send us an email and we’ll say what we think.
