New-build mastic & snagging in Lane End, Hampshire
Professional new build mastic in and around Lane End, with old sealant always removed completely and a one-year guarantee.
- Joints pulling apart as timber shrinks
- Leaking shower tray seals in a new home
- Sealant work across a run of new homes
How to look after the new joints
Looking after new joints is easy, and it makes a real difference:
- Check bath and shower seals every few months as the house settles
- Wipe joints with warm soapy water
- Resist patching a failed seal with a tube from the DIY shop
- Do not wait for the house to settle if water is getting through
Avoid standing on the rim of the bath or the edge of the tray in the first few weeks. If a bath or tray moves when you stand in it, get it looked at.
Early snagging is easier snagging. Small faults turn into leaks if left in a busy bathroom.
About our new build mastic in Lane End
Failed shower seals, gaps along the skirting and messy beads are common items on a new-home snagging list. If you’re still within the builder’s snagging or warranty period, tell them first, and if it is not put right, get in touch with us. If you have messy sealant that spoils new finishes and sealant that never bonded to the surface, we can put it right, on kitchens, plot handovers and show homes alike.
Somewhere as small as Lane End, new homes tend to be conversions, self-builds or a few houses rather than an estate. Each still needs its sealant and floor joints finished properly.
A 12-month guarantee comes with the work, just as it does everywhere we cover.

Can I do it myself?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
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 does not work out, we can still put it right.

Why it’s worth doing now in Lane End
Running a new bead over the builder’s sealant might look tidy for a few weeks, but it will not bond to the old layer. Taking it all out and starting again is the only way to get a lasting seal. In a small place like Lane End, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Instead of a standard rate, we look at what your job involves: how many joints, what’s in them now and how we reach them. You’ll know the price before we begin.
Why us?
- A 12-month guarantee on all work
- White, clear, grey or coloured to suit, where the product allows
- 20+ years of sealant experience
- Rated 4.9 stars on Google

When to call us in Lane End
The first winter with the heating on dries a new home quickly. Gaps open along skirting, frames and worktops and cracked sealant shows up.
These are the problems we’re asked about most:
- New-build shower sealant that has already split
- Joints pulling apart as timber shrinks
- Second-fix sealing on new plots
- Kitchen sealant that has pulled off the wall
Whether the job is in Lane End itself or nearby, the right material for each joint matters as much as a neat finish.

Lane End questions
Will you come out to Lane End?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
What guarantee comes with new build mastic in Lane End?
All our work, in Lane End and everywhere else, comes with a 12-month guarantee. We’re also fully insured and ARBOMaster approved.
Do you work through snagging lists?
Yes. We often work straight from a snagging list. We’ll go through the sealant items and agree what we’ll do.
Can tenants book the work?
Yes, but check with your landlord or agent first. Landlords are often happy for the work to be arranged.
Where are you based?
Our base is in Crawley, West Sussex, and we work across South East England, London and Scotland.
Is there any odour?
That depends on the sealant. Some products have a noticeable smell, others very little, and any smell fades as they cure.
Do you take on second-fix sealing for builders?
Yes. Second-fix sealing in bathrooms, kitchens, frames and floors is part of what we do. We clean and prime joints properly to keep callbacks down.
Which products do you use?
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 will explain our choice.
What we do, step by step
When we get to you, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. Most jobs then take a few hours for most snagging lists, longer for a run of plots. Somewhere like Lane End needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- We look at why each joint failed, including any movement.
- We remove the failed sealant and clean the joints.
- Joints are dried and primed where the product calls for it.
- New sealant goes in, with baths filled first so they’re at their heaviest.
- The finished joints are checked and the cure times given.
Getting ready for the visit
- Where the joints are inside, avoid wetting them before we arrive
- On commercial sites, let us know about site rules
- Clear items away from the joints we’re working on
