Whiteley New Build Mastic
We cover Whiteley for plot mastic for developers and snagging failed sealant in new homes. Old sealant removed completely, joints prepared properly.
- Kitchen sealant that has pulled off the wall
- Leaking shower tray seals in a new home
- Smeared, uneven beads picked up at snagging
Why it’s worth doing now in Whiteley
If you are still in the builder’s snagging or warranty period, ask them to put it right first. If it’s slow, or the same joint keeps failing, a proper reseal from a specialist is the next step. Homes in smaller places like Whiteley can face more weather, and failed outside joints let damp into walls. Inside, a split seal lets water into floors and panels just as it would anywhere.
Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.

New build mastic in Whiteley
Across Whiteley, we work for both new-home owners and the builders handing those homes over. One shower or a whole phase of plots, the method does not change: cut out, clean, prime where needed and reseal neatly. If you are dealing with new-build shower sealant that has already split and messy sealant that spoils new finishes, we can put it right, on windows & doors, show homes and skirting & floors alike.
In and around Whiteley, floors range from older timber boards to tiles and newer finishes, each moving in its own way. The sealant at skirtings and thresholds has to suit the floor it meets.
We stand behind the work with a one-year guarantee, so you are covered after we have gone.

How to look after the new joints
No joint lasts for ever, but care makes a real difference. A few tips:
- Raise failed sealant with the developer while you are covered
- Wait for the cure time before using a resealed shower
- Get a leaking seal dealt with straight away
- Avoid scourers and strong chemicals on sealant
Ventilation matters in a new home, which is still drying out. Use the extractor fan or open a window after showers to help keep mould away.
The sooner you deal with untidy or cracking sealant, the less there is to put right. Left alone, a small crack can become a leak.
What affects the quote in Whiteley
Some jobs are bigger than they look, and some smaller. What affects the quote:
- How much old sealant there is and how hard it is to remove
- Working hours on commercial sites
- The product the joint needs
- How much there is to do
What you pay reflects the work, not guesswork. That’s why we ask a few questions first and give you a clear quote before work begins.
Asking for a quote
What to tell us when you ask for a quote:
- The problem you’ve noticed
- The rough size of the job
- The type of property
- Any previous sealing or DIY work
Asking for a quote is easy: let us know the job and the location, and roughly how big it is. A few pictures by email make the job easier to understand.
The process
All our tools and materials come with us in the van, so you don’t need to buy or prepare anything. After a quick look at the joints together, we protect the area and start. Most jobs take a few hours for most snagging lists, longer for a run of plots. In a smaller place like Whiteley, parking is seldom the issue; lanes, gates and long drives are worth mentioning. For outside work, side access and the height of the joints help us plan.
- We start by going through the snagging items or plot schedule with you.
- Every bit of the old builder’s sealant is cut out.
- 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.
Preparing for the visit
- Keep children and pets away from the work area
- Tell us about any water getting in
- On commercial sites, let us know about site rules

Honest limits
Before you book, it’s worth knowing the limits:
- Your warranty claim itself, which is between you and the builder
- Leaks from pipes, valves or wastes, which need a plumber
- Cracking that points to a structural problem
Not sure which it is? You can call 0345 464 0079 or email us and we’ll tell you honestly.

Should I try it myself first?
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly.

Surface by surface
Kitchens
Beside the sink, the joint takes water every day. A kitchen sealant goes in there, food-safe where it’s needed.
