New build mastic in Liphook
New homes move as they dry out. Timber shrinks, plaster dries and baths and trays bed down, so sealant that was laid quickly before handover often cracks. Typical jobs include gaps opening as the house dries out and settles and gaps between new skirting and floors, on bathrooms & en suites, show homes and plot handovers.
For a new home in or near Liphook, it’s worth checking the sealant early. Gaps at skirtings, shower seals pulling away and missing mastic around frames are common snags.
Big or small, you get the same one-year guarantee in Liphook and across Hampshire.

Why it’s worth doing now in Liphook
If you’re still in the builder’s snagging or warranty period, ask them to put it right first. If it keeps failing or isn’t dealt with, we can reseal it properly. In an older home around Liphook, damp from a failed joint can get into timber and plaster, and that is a much bigger job than renewing the sealant.
Leaving a failed joint usually makes the job bigger, not smaller. If you are unsure, phone 0345 464 0079 or email us and we will give you an honest view and a quote.
Why us?
- We leave the area clean and tidy
- Sealant colour chosen to suit
- A choice of colours where the product allows
- An ARBOMaster approved applicator

Liphook: your questions answered
I let a flat near Liphook station. Can you help?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. You can phone 0345 464 0079 or email us with the details for a clear quote.
Can you do new build mastic in Liphook?
Yes. We work across London and the South East, and Liphook is part of that. Just phone 0345 464 0079 or send us an email with a few details of the job, and we’ll give you a clear price.
Why has my new-build shower seal failed already?
There are usually two causes: the house moving as it dries, and sealant that never bonded properly. A proper reseal deals with both.
Do I need to be at home?
If the work is inside, we need someone to let us in. Once we have agreed the job, you do not need to watch us work.
Do you work for developers?
Yes. We take on second-fix sealant work across new plots. We clean and prime joints properly to keep callbacks down.
Will you just run a new bead over the existing one?
No. Sealing over old sealant looks fine for a few weeks, then lifts. We remove every bit of the old bead before resealing.
Do you do commercial work?
Yes, regularly. Larger jobs can be planned room by room or area by area to suit the site.
Where do you work from?
We are a Crawley-based firm, with over 20 years’ experience. Our area covers South East England, London and Scotland.

What else we do in Liphook
How the visit works
The work is kept neat and contained to the area we’re working on. Expect the work to take a few hours in a single home, and we explain the cure time before we leave. A visit to Liphook is planned like any other: the time, the access and where to park are agreed in advance. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- First we work through your snagging list or plot schedule with you.
- Failed or untidy sealant is cut out completely.
- We clean off dust from the build and prime the surfaces where the product needs it.
- We apply a sealant that suits each joint and tool it to a neat finish.
- We check every joint and tell you how long each needs to cure.
Preparing for the visit
- Keep children and pets away from the work area
- Tell us about any water getting in
- Try not to wet indoor joints just before the visit
Getting a quote
Asking for a quote is easy: let us know the job and the location and its rough size. A few pictures by email make the job easier to understand.
Advice
DIY sealant or a professional job?
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
