New build mastic in Beech
Some owners wait for the first year’s movement before having joints redone. For small cosmetic gaps, that is reasonable, but a failed shower or bath seal shouldn’t wait. If you’re dealing with shower seals failing in the first year or two and plot mastic for developers ahead of handover, we can put it right.
Around Beech, older homes often have timber floors that move through the year, which is why skirting and threshold joints need a flexible sealant, not filler.
Your job is guaranteed for a year, as with all our work.

How the visit works
When we get to you, we check the joints match what you told us. If anything is different, we explain it before carrying on. Most jobs then take a few hours for most snagging lists, longer for a run of plots. In a small place like Beech, access is usually the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- Each joint is checked for movement before any work starts.
- We remove the failed sealant and clean the joints.
- Joints are dried and primed where the product calls for it.
- Baths are filled with water, then the new sealant is applied.
- We check every joint and leave you with the cure times.
Preparing for the visit
- Let us know about earlier repairs to the joints
- Let us know about stairs, lifts or work at height
- Move anything stored near the joints

Advice
When to call us in Beech
Sealant is often one of the last jobs before handover. Joints are not always cleaned of dust or primed, and the sealant sits on grit instead of the surface.
Look out for any of the following:
- Internal frame sealant that has split
- New-build shower sealant that has already split
- Joints pulling apart as timber shrinks
- Skirting joints opening in the first winter
If you’ve bought a new home near Alton station, the sealant around baths, showers and frames is worth checking in the first year or two.
What to look for in a quote
- What happens if the job turns out different
- How the colour is chosen
- Whether the sealant suits the joint
- What the cure time is
How to look after the new joints
So the new joints stay in good condition:
- Record problems with dated pictures
- Get a leaking seal dealt with right away
- Keep water off fresh sealant until it has cured
- Don’t seal over failed sealant yourself
Keep an eye on the joints over the first couple of years. Hairline gaps can open as timber and plaster dry, and they’re simple to reseal once movement has slowed.
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.
New homes and floors in Beech
Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.

Common questions in Beech
Do you cover smaller places like Beech?
Yes, we do. 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 you cover Beech for new build mastic?
Yes. Our work covers London and the South East, and Beech is part of that. Just ring 0345 464 0079 or drop us an email with a few details of the job.
Can new sealant go on top of the old bead?
No. New silicone won’t bond to old silicone, so sealing over the top fails quickly. The old sealant always comes out first.
How do I get a quote for new build mastic in Beech?
We don’t publish prices, because the cost depends on the job: how much there is, what’s there now, how we reach it and what it needs. We agree the price before any work begins.
Is there any odour?
Some sealants have a smell while they cure, which fades as it sets. Opening a window helps.
Do you remove the old sealant?
Yes, every time. New sealant won’t bond properly to old, so the joint is cleaned back first.
Where do you work from?
We work from Crawley. Our applicators cover Beech, along with the rest of our area.
Can I send you my snagging list?
Yes. Snagging lists are a common starting point for us. We agree the sealant items with you before we start.
Landlord and commercial work in Beech
Whether it’s one flat or a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.

How the job changes by surface
Kitchens
Beside the sink, the joint takes water every day. We use a sealant suited to kitchens, food-safe where it’s needed.
Plot handovers
Developers can send the plot schedule and specification for a quote. Sealant work across the plot is covered to the agreed spec.
Can I do it myself?
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
What affects the cost of new build mastic
There’s no set price list, because jobs vary so much. The quote depends on:
- Whether there’s mould to deal with
- The product the joint needs
- Whether old sealant or filler has to be cut out
- Access and height
What it costs depends on the amount of work, how hard the old material is to remove and access to the work. We give a clear quote before we start.
