How we handle new build mastic in Hattingley
Across Hattingley, we work for both new-home owners and the builders handing those homes over. One shower or a whole phase of plots, the method doesn’t change: cut out, clean, prime where needed and reseal neatly. Common call-outs are for cracked caulk along new skirting and shower seals failing in the first year or two, across bathrooms & en suites, plot handovers and show homes.
Around Hattingley, older homes often have timber floors that move through the year, which is why skirting and threshold joints need a flexible sealant, not filler.
Every job comes with our one-year guarantee.

How we quote for new build mastic
The quote reflects the job in front of us. We take into account:
- Working hours on commercial sites
- The amount of work
- How many rooms, windows or areas are involved
- Whether the work is at height
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.
What we need to know
When you call or email, it’s useful to know:
- If it’s domestic, commercial or a hotel
- What’s wrong with the joints now
- If someone has resealed it before
- Roughly how big the job is
We quote each job on its own, so the first step is telling us about yours. Simply phone 0345 464 0079 or drop us an email and describe the job and send photos if you have them.
Should I try it myself first?
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
New build mastic around Hattingley

Related advice
What the job involves on each surface
Windows and doors
Draughts around new frames are often a sealant gap. We look at the joints and reseal where needed.
Kitchens
Beside the sink, the joint takes water every day. We use a sealant suited to kitchens.
How to look after the new joints
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Wait for the cure time before using a resealed shower
- Record problems with dated photos
- Ventilate bathrooms well, especially in the first year
- Get a leaking seal dealt with right away
Keep the bathroom ventilated, especially in the first year. Use the extractor fan or open a window after showers.
Do not let the snagging period run out with sealant problems unreported. Once it ends, the repair may be down to you so report it promptly.
