New build mastic in Broughton
If your new home has a leaking shower seal, open skirting joints or untidy sealant, we can help. While the builder’s snagging or warranty period runs, report it to them first, and if it is not put right, get in touch with us. We work on bathrooms & en suites, windows & doors and plot handovers, and people most often call us about sealant applied over dusty or wet surfaces and plot mastic for developers ahead of handover.
In and around Broughton, floors range from older timber boards to tiles and newer finishes, each moving in its own way. Skirting and threshold joints need a sealant that suits the floor.
A 12-month guarantee comes with the work, just as it does everywhere we cover.

Looking after it afterwards
Once the sealant has cured, a few habits help it last:
- Watch for new gaps as the house dries out
- Do not seal over failed sealant yourself
- Do not wait for the house to settle if water is getting through
- Put sealant faults on your snagging list early
Leave the sealant for the cure time we give you before showering or bathing. Most silicones need around a day to cure enough for use.
A failed seal in a new home lets water into joists, plasterboard and ceilings. Catching it early keeps the fix to the sealant and protects the rest of the house.
Can I do it myself?
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
What happens if it’s left?
Running a new bead over the builder’s sealant might look tidy for a few weeks, but it cannot bond to what’s underneath. A lasting seal starts with removing the old one completely. Around Broughton, water from a failed joint in an older home can soak into timber and plaster, which is far harder to put right than the sealant itself.
What it costs depends on the amount of work, how much old material has to come out and access to the work. We give a clear quote before work begins.

What affects the cost of new build mastic
Every job gets its own quote. These are the things that affect it:
- The type of sealant required
- How easy the joints are to reach
- The old material and how stubborn it is
- Working hours on commercial sites
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.
What we need to know
The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:
- The problem you’ve noticed
- Photos by email, if that is easy
- Any previous sealing or DIY work
- How many joints, rooms or windows are involved
The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints.
