Questions from Farleigh Wallop
Do you work for landlords with property near Basingstoke station?
Yes, rental work is part of what we do. You can call 0345 464 0079 or send us an email with the address and a few details, and we will give you a fixed price before work begins.
Will you come out to Farleigh Wallop?
Yes, Farleigh Wallop is covered. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Do I have to be there?
For indoor joints, yes, someone needs to let us in. Once we’ve agreed the job, you don’t need to watch us work.
Do you guarantee your work?
Yes, always. Each job is guaranteed for twelve months.
What do you put in the joint?
We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference, and we’ll explain our choice.
Is it normal for sealant to crack in a new home?
It’s common, and there are generally two reasons: movement as the house dries and settles, and sealant laid onto dust without primer. A proper reseal deals with both.
What colour sealant will you use?
We use white, clear or a colour to suit the finishes. Let us know your preference when you ask for a quote.
Can new sealant go on top of the old bead?
No. Fresh silicone doesn’t stick to the old layer, so sealing over the top fails quickly. The old sealant always comes out first.
How we handle new build mastic in Farleigh Wallop
New homes move as they dry out. Timber shrinks, plaster dries and baths and trays bed down, and sealant applied in a hurry at handover can split. If you are dealing with beads laid onto grit and dust from the build and cracked sealant around new window and door frames, we can help, on bathrooms & en suites, windows & doors and plot handovers alike.
Older homes in small places like Farleigh Wallop often have timber floors that move with the seasons, so skirting and threshold joints need a flexible sealant rather than a rigid filler.
All our work comes with a 12-month guarantee.

Advice
Signs you need new build mastic in Farleigh Wallop
A new house holds a lot of water from the build, which takes a year or two to dry out. As it does, timber shrinks and joints open and the sealant has to cope with the movement.
These are the problems we are asked about most:
- Smeared, uneven beads picked up at snagging
- Gaps behind new kitchen upstands
- Plot mastic for developers ahead of handover
- Joints pulling apart as timber shrinks
In and around Farleigh Wallop, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.
What to look for in a quote
- What the cure time is
- Which colour the sealant will be
- What happens if the job turns out different
- Whether the sealant suits the joint
Keeping the joints in good condition
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Wait for the cure time before using a resealed shower
- Look at the sealant regularly in the first couple of years
- Get a leaking seal dealt with right away
- Do not seal over failed sealant yourself
Wipe the sealant with warm soapy water. Avoid abrasive pads and strong solvents.
If a shower tray or bath seal splits in the first year, look for movement. Getting it resealed properly, and any movement checked, stops it recurring.
Quotes for new build mastic in Farleigh Wallop
We quote each job individually. These are the things that affect it:
- The number and length of the joints
- The old material and how stubborn it is
- How many rooms, windows or areas are involved
- Working hours on commercial sites
What you pay reflects the work, not a rough estimate. That’s why we ask a few questions first and send you a clear quote before any work starts.
What we need to know
There’s no need for technical detail. Just tell us:
- Any previous sealing or DIY work
- What’s wrong with the joints now
- Access, such as stairs, a lift or height
- The address or postcode of the job
Need a quote? Please phone 0345 464 0079 or drop us an email with a few details. You will know what we plan to do, and what it will cost, before any work begins.
DIY versus a professional finish
If you’ve already had a go yourself, that’s fine. We cut it out and start again, so tell us about it when you ask for a quote.
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
