Common questions in Wivelrod
Do you cover Wivelrod for new build mastic?
Yes, Wivelrod is within the area we cover. We work across London and the South East. Just call 0345 464 0079 or email us with a few details of the job, and we will send you a clear quote.
Will you come out to Wivelrod?
Yes, Wivelrod is covered. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Do you guarantee your work?
Yes. Each job is guaranteed for twelve months, large or small.
Can I add another job to the visit?
Of course. Combining jobs makes good use of the visit.
Will you just run a new bead over the existing one?
No. New silicone won’t bond to old silicone, so sealing over the top fails quickly. The old sealant always comes out first.
How long should I leave it?
Many sealants skin over quickly but take longer to cure fully. We’ll tell you how long to leave the joint before we leave.
What do you need from me for a quote?
The location, the problem and the rough size of the job. If you can, email a few photos.
Do you work through snagging lists?
Yes. Snagging lists are a common starting point for us. We’ll go through the sealant items and agree what we will do.
New build mastic for homes and businesses in Wivelrod
Our new-build work comes in two parts: plot mastic for developers, and putting right failed sealant for people who’ve bought a new home. Both get the same care over preparation, because that’s what rushed new-build sealant usually lacks. Typical jobs include sealant applied over dusty or wet surfaces and worktop and upstand sealant coming away, across kitchens, bathrooms & en suites and show homes.
Work in a small place like Wivelrod just needs the journey and access planning, and once on site, the job is the same as anywhere.
All our work comes with our one-year guarantee, wherever you are in Hampshire.

What we cannot put right
New sealant cannot fix everything, and we will tell you before any work starts. Sealant won’t put right:
- Plumbing faults behind the sealant
- Baths and trays that move too much for sealant to cope with
- Cracked trays, tiles or worktops
If in doubt, ring 0345 464 0079 or send us an email and we’ll say what we think before booking.
Surfaces we seal
- Skirting & floors
- Show homes
- Bathrooms & en suites
- Windows & doors
- Plot handovers
- Kitchens
What happens if it’s left?
Running a new bead over the builder’s sealant might look tidy for a few weeks, but it will not bond to the old layer. Taking it all out and starting again is the only way to get a lasting seal. Older cottages and farmhouses around Wivelrod can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
The cost depends on the amount of work, how much old material has to come out and access to the work. You will have a clear quote before any work starts, so you know where you stand.

How we quote for new build mastic
Call for a quick quote. The main things that affect it are:
- The product the joint needs
- Working hours on commercial sites
- Access and height
- The old material and how stubborn it is
Every job is a little different, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all play a part.

- Any previous sealing or DIY work
- Roughly how big the job is
- Any access issues, like height or stairs
- Where the job is, and your postcode
Getting a quote is simple: let us know what needs doing and where and its rough size. Photos by email help us understand the job, and we will take it from there.
What we do, step by step
The work is kept neat and contained to the joints we are treating, so you can carry on as normal. Expect the work to take a few hours in a single home, and we tell you how long to leave it before we go. Somewhere like Wivelrod needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- The failed sealant is removed completely, with no layer left behind.
- We clean out the dust and grit left from the build.
- Primer goes on where the surface and product need it, then the new sealant.
- Each bead is tooled and the cure times explained.
How to prepare
- Mention any tricky access
- Keep pets and children clear of the area while we work
- Tell us if parking is tricky

Advice
Surface by surface
Show homes
We seal show-home bathrooms, kitchens and frames ready for viewings. Tell us when the home is open so we can plan around it.
Skirting and floors
Floors and skirting move as the house dries and the heating runs. Caulk cracks; a flexible sealant moves with it.
How to look after the new joints
Looking after new joints is easy:
- Ventilate bathrooms well, especially in the first year
- Watch for new gaps as the house dries out
- Avoid scourers and strong chemicals on sealant
- Avoid running a DIY bead over the old one
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.
Report failed sealant to the builder while you are in the snagging period. Once it ends, the repair may be down to you so report it promptly.
Common problems we fix in Wivelrod
New homes are full of moisture from plaster, screed and concrete, which takes a year or two to dry out. As it does, timber shrinks and joints open, and sealant that cannot keep up splits.
It’s worth asking for a quote if you see:
- Plot mastic for developers ahead of handover
- Skirting joints opening in the first winter
- Leaking shower tray seals in a new home
- Cracked sealant around new window and door frames
In and around Wivelrod, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.
