How we handle new build mastic in Upper Clatford
A new build should have a neat, sound bead at every joint. Smeared, patchy or cracked sealant is worth sorting early, before water reaches anything behind it. We work on show homes, skirting & floors and windows & doors, and common reasons people get in touch are kitchen sealant that has pulled off the wall and skirting joints opening in the first winter.
For a small place like Upper Clatford, the journey and access are planned in advance, and once on site, the job is the same as anywhere.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we will sort it.

Honest limits
Honest advice matters more to us than a booking, so here’s what new sealant will not do:
- Your warranty claim itself, which is between you and the builder
- Baths and trays that move too much for sealant to cope with
- Cracked trays, tiles or worktops
If in doubt, phone 0345 464 0079 or send us an email and we will say what we think.

Signs you need new build mastic in Upper Clatford
New homes are full of moisture from plaster, screed and concrete, and it dries out over the first couple of years. Drying timber shrinks and pulls joints apart and the sealant has to cope with the movement.
People generally contact us when they notice one of these:
- Plot mastic for developers ahead of handover
- Leaking shower tray seals in a new home
- Sealant that never bonded to the surface
- Messy sealant that spoils new finishes
For new homes near Andover station, it’s worth checking the sealant early, while snags are still fresh.
Questions to ask before booking
- Who turns up on the day
- How the joint is cleaned and prepared
- What guarantee comes with the work
- Is VAT in the price?
Aftercare tips
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Keep pictures and emails about snagging items
- Do not seal over failed sealant yourself
- Watch for new gaps as the house dries out
- Wait for the cure time before using a resealed shower
Clean the sealant with a mild detergent and a soft cloth. Keep scourers and harsh chemicals off it.
Report failed sealant to the builder while you are in the snagging period. Once it ends, the repair may be down to you, so raise it early.
How the visit works
Before we leave, we go over the finished joints with you and explain the cure time. The visit itself normally takes a few hours for most snagging lists, longer for a run of plots, depending on the size of the job. In a small place like Upper Clatford, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- Each joint is checked for movement before any work starts.
- 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.
Getting ready for the visit
- Try not to wet indoor joints just before the visit
- Let us know about earlier repairs to the joints
- Mention any parking rules near the property

Advice
What affects the quote in Upper Clatford
Every job gets its own quote. This is what makes a difference:
- Any working-time requirements on site
- The number and length of the joints
- Whether old sealant or filler has to be cut out
- Which sealant suits the joint
The cost depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before work begins, so you know where you stand.
Asking for a quote
You don’t need to know the technical terms. It helps if you can tell us:
- Pictures of the joints, sent by email
- What’s wrong with the joints now
- Any previous sealing or DIY work
- The address or postcode of the job
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints.
