What affects the quote in Ware
Jobs vary more than people expect. The main factors:
- The number and length of the joints
- How many areas need sealing
- Which sealant suits the joint
- Working hours on commercial sites
A few things move the cost up or down: 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
What to tell us when you ask for a quote:

How we handle new build mastic in Ware
We work in new homes and on new-build sites across Ware. Whether it’s one en suite or a run of plots, the method is the same: cut out, clean, prime where needed and reseal neatly. Typical jobs include gaps behind new kitchen upstands and gaps opening as the house dries out and settles, on skirting & floors, kitchens and show homes.
Towns like Ware have older streets and newer estates side by side. In a newer home, sealant and floor joints are usually among the first things to need attention.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we’ll sort it.

What we do, step by step
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. Typically it takes a few hours for most snagging lists, longer for a run of plots and we leave things clean and tidy. A visit in Ware needs access to the work and a place to park close by. For outside work, let us know about side access, gates and any upper-floor joints.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- The failed sealant is removed completely down to clean surfaces.
- Joints are vacuumed and cleaned of building dust.
- Primer goes on where the surface and product need it, then the new sealant.
- Each bead is tooled and the cure times explained.
Before we arrive
- Keep pets and children clear of the area while we work
- Tell us about any water getting in
- Where the joints are inside, avoid wetting them before we arrive

Ware questions
Can you do new build mastic in Ware?
Yes. Our work covers London and the South East, and Ware is part of that. You can phone 0345 464 0079 or send us an email and tell us what needs doing.
Is there a guarantee on new build mastic in Ware?
All our work, in Ware and everywhere else, comes with a 12-month guarantee. We’re fully insured, and an ARBOMaster approved applicator.
Do the sealants smell?
Possibly a little. Any smell clears as the sealant cures, and ventilation helps.
My new home is still under warranty. Should I contact you?
If you are still within the builder’s snagging or warranty period, report it to them first. If they’re slow or the fix does not last, we can help.
What sealant do you use?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.
Is it worth trying it myself?
You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. If it does not work out, we can redo it.
Can you match the sealant colour to my new kitchen or bathroom?
Most bathroom joints are white or clear, but sealant comes in other colours too. We match the colour to the finish before we begin.
Do you hold any approvals?
Yes. We’re approved under the ARBOMaster scheme.

How the job changes by surface
Show homes
Tired or marked sealant in a show home can be renewed. The old bead comes out and a clean new one goes in.
Bathrooms and en suites
En suite seals are easy to miss on a snagging list until they leak. Resealing properly keeps water where it belongs.
Common problems we fix in Ware
Baths and trays settle under load once the home is lived in. If a bath wasn’t filled when it was sealed, the bead is stretched the first time it’s used.
Keep an eye out for these signs:
- Untidy sealant flagged on a snagging list
- Gaps between new skirting and floors
- Second-fix sealing on new plots
- Frame joints opening as the plaster dries
Around Ware, as everywhere, new build mastic is only as good as the preparation behind it.
What your quote should include
- How much experience the applicator has
- How the joint is cleaned and prepared
- What the quote includes, VAT included or not
- How long the guarantee is
Leave it or put it right?
Resealing everything on a snagging list in one visit is normally simpler than chasing joints one at a time. You get one visit and one clear quote to plan around. In Ware, as anywhere, most leaks start as a small gap in a joint, and they’re far easier to fix early.
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.
