New build mastic for homes and businesses in Hastingleigh
Our new-build work comes in two parts: plot mastic for developers, and putting right failed sealant for people who’ve bought a new home. In both, preparation makes the difference. If you’re dealing with worktop and upstand sealant coming away and cracked caulk along new skirting, we can help, on show homes, plot handovers and bathrooms & en suites alike.
Older homes in small places like Hastingleigh often have timber floors that move with the seasons, so skirting and threshold joints need a flexible sealant rather than a rigid filler.
You get a one-year guarantee, the same in Hastingleigh as everywhere else we work.

What we do, step by step
When we arrive, we start by going over the job with you. Surfaces next to the work are protected before any work begins. The work usually takes a few hours for most snagging lists, longer for a run of plots. Somewhere as small as Hastingleigh, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- Each joint is checked for movement before we start.
- 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.
- We check every joint and leave you with the cure times.
How to prepare
- Mention any leaks or damp you’ve noticed
- Mention if the joints have been sealed before
- Mention any sign-in or site rules at work premises

What else we do in Hastingleigh
How we quote for new build mastic
The price is agreed before any work begins. It takes into account:
- Which sealant suits the joint
- The amount of work
- The number of rooms or windows
- When we can work, for business premises
Doing several joints on one visit normally makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. You’ll get one clear quote for the whole job.
Asking for a quote
What to tell us when you ask for a quote:
- Whether it has been sealed before
- Roughly how big the job is
- Where the job is, and your postcode
- Any access issues, like height or stairs
Every job is quoted individually, so the first step is telling us about yours. Just phone 0345 464 0079 or drop us an email with the details and send pictures if you have them.
What the job involves on each surface
Plot handovers
Developers can send the plot schedule and specification. Sealant work across the plot is covered to the agreed spec.
Show homes
Tired or marked sealant in a show home can be renewed. We cut it out and reseal neatly.
DIY versus a professional finish
If you’ve already had a go yourself, that’s fine. We cut it out and start again.
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.
Hastingleigh: your questions answered
I let a flat near Wye station. Can you help?
Yes. We work for letting agents and landlords as well as householders. You can ring 0345 464 0079 or send us an email with the details for a clear quote.
Do you cover Hastingleigh for new build mastic?
Yes, Hastingleigh is within the area we cover. Our work covers London and the South East. Just phone 0345 464 0079 or email us with a few details of the job.
Why has my new-build shower seal failed already?
There are generally two causes: the house moving as it dries, and sealant that never bonded properly. Cutting it out and resealing properly fixes both.
Should I wait before resealing?
Any seal that’s leaking should be redone straight away. Cosmetic gaps can wait until the first year or two of movement has passed.
Are you an approved applicator?
Yes. Mr Mastic is an ARBOMaster approved applicator and we are fully insured too.
Should I try DIY first?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs.
Do you take on second-fix sealing for builders?
Yes. We take on second-fix sealant work across new plots. We clean and prime joints properly to keep callbacks down.
Does someone need to be in?
For indoor joints, yes, someone needs to let us in. Once we’ve agreed the job, you do not need to watch us work.
When something else is needed
A few problems are outside what sealant work can do:
- Deciding who is responsible under a builder’s warranty
- Movement caused by a poorly fitted tray or bath
- Settlement cracks that need a surveyor
If you are not sure, just phone 0345 464 0079 or send us an email and we will give you a straight answer.

Common problems we fix in Hastingleigh
Sealant applied onto damp surfaces doesn’t bond well. On a busy site, joints aren’t always given time to dry before the sealant goes on.
Signs it’s time to call us include:
- Sealant applied over dusty or wet surfaces
- Skirting joints opening in the first winter
- New-build shower sealant that has already split
- Cracked sealant around new window and door frames
Around Hastingleigh, as everywhere, new build mastic is only as good as the preparation behind it.

Why act early in Hastingleigh
Small cosmetic gaps can wait for the house to settle, but water getting through cannot. If you’re unsure which you have, call 0345 464 0079 or email us with photos and we’ll give you a straight answer. In a small place like Hastingleigh, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
The cost depends on the amount of work, how hard the old material is to remove and access to the work. You will have a clear quote before any work starts, so you know where you stand.

- 20+ years of sealant experience
