About our new build mastic in West Challow
Some owners wait for the first year’s movement before having joints redone. That makes sense for small gaps that are just cosmetic, but a failed shower or bath seal shouldn’t wait. We’re often asked to deal with cracked caulk along new skirting and cracked sealant around new window and door frames, on bathrooms & en suites, show homes and kitchens.
Older homes in small places like West Challow often have timber floors that move with the seasons, which is why skirting and threshold joints need a flexible sealant, not filler.
We stand behind the work with a one-year guarantee, so you’re covered after we’ve gone.

How we quote for new build mastic
There’s no set price list, because jobs vary so much. What we look at:
- Access and height
- How many areas need sealing
- How much there is to do
- Whether old sealant or filler has to be cut out
No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part.
What we need to know
A few details help us give you an accurate quote. When you ask for a quote, tell us:
- The address or postcode of the job
- The problem you’ve noticed
- Any previous sealing or DIY work
- Whether it’s a home or a business
Getting a quote is simple: tell us what needs doing and where and its rough size. Photos by email help us understand the job, and we will take it from there.
Signs you need new build mastic in West Challow
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.
Any of these means the joints need attention:
- Beads laid onto grit and dust from the build
- Second-fix sealing on new plots
- Smeared, uneven beads picked up at snagging
- Frame joints opening as the plaster dries
Whether the job is in West Challow itself or nearby, the right material for each joint matters as much as a neat finish.
Before you book anyone
- Whether VAT is included
- What the cure time is
- The length of the guarantee
- Whether they seal over old material or remove it
Should I try it myself first?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
When something else is needed
Sealant is not the answer to every problem, and we’ll tell you before any work starts. Sealant won’t put right:
- Deciding who is responsible under a builder’s warranty
- Plumbing faults behind the sealant
- A tray or bath that is not properly supported, until it’s fixed
If you’re not sure, just ring 0345 464 0079 or send us an email and we’ll give you a straight answer before you book.
What we seal
- Skirting & floors

Aftercare tips
Simple care keeps the joints in good condition. Our advice:
- Act quickly if a seal starts to leak
- Wait for the cure time before using a resealed shower
- Ventilate bathrooms well, especially in the first year
- Avoid running a DIY bead over the old one
Ventilation matters in a new home, which is still drying out. Use the extractor fan or open a window after showers.
If a shower tray or bath seal splits in the first year, look for movement. Have it resealed, and the tray or bath checked, before it gets worse.
FAQs for West Challow
Will you come out to West Challow?
Yes. West Challow is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Do you cover West Challow for new build mastic?
Yes, West Challow is within the area we cover. We work across London and the South East. You can phone 0345 464 0079 or email us and let us know what needs doing.
Can tenants book the work?
Of course. Ask your landlord first, and we can send them the quote if that helps.
Do you work for letting agents?
Yes, regularly. Several properties can be quoted together, and between tenancies is a good time for the work.
When is the sealant fully cured?
It depends on the product and the conditions. We tell you how long to leave it before we go.
Can you do several jobs on one visit?
Yes, and it often makes sense. Doing several areas at once is generally more efficient, so mention them when you ask for a quote.
Is there any odour?
That depends on the sealant. Some smell for a while, some hardly at all, and any smell fades as they cure.
Why does sealant fail so quickly in new builds?
It’s common, and there are generally two reasons: movement as the house dries and settles, and sealant laid onto dust without primer. Cutting it out and resealing properly fixes both.
How the visit works
All our tools and materials come with us in the van, so there’s nothing for you to buy. Once we’ve agreed what’s being done, the area is protected and the work begins. It normally takes a few hours in a single home. For a village or hamlet like West Challow, the journey is planned in advance: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- We start by agreeing which joints are on the list, from the snagging sheet or plot schedule.
- We cut out every bit of the failed or messy sealant.
- We clean off dust from the build and prime the surfaces where the product needs it.
- A sealant chosen for each area goes in and is tooled smooth.
- Finally, each room is checked and you are given the cure time.
Preparing for the visit
- Clear items away from the joints we are working on
- Keep pets and children clear of the area while we work
- Mention any parking rules near the property
