About our new build mastic in Lowford
Across Lowford, we work for both new-home owners and the builders handing those homes over. Whether it’s one en suite or a run of plots, the method is the same: remove, clean, prime where needed, then a neat new bead. We work on kitchens, bathrooms & en suites and plot handovers, and common reasons people get in touch are untidy sealant flagged on a snagging list and internal frame sealant that has split.
Where new homes go up in smaller places like Lowford, it’s often a small development or a single plot. The sealant around baths, showers, frames and skirtings needs to be right from the start.
Whatever the size of the job, it’s backed by our 12-month guarantee in Lowford and across Hampshire.

Common problems we fix in Lowford
If plaster or screed was still damp when it was sealed, the bond suffers. Site programmes do not always leave time for joints to dry.
The most common problems we see are:
- Kitchen sealant that has pulled off the wall
- Beads laid onto grit and dust from the build
- Sealant work across a run of new homes
- Leaking shower tray seals in a new home
Around Lowford, as everywhere, new build mastic is only as good as the preparation behind it.

Do you cover Lowford for new build mastic?
Yes. We work across London and the South East, and Lowford is part of that. Just ring 0345 464 0079 or email us with a few details of the job.
What information do you need?
The location, the problem and the rough size of the job. Photos by email help too.
How do I get a quote for new build mastic in Lowford?
We do not publish prices, because the cost depends on the job: how much there is, what’s there now, how we reach it and what it needs. You will get a clear quote before work begins.
Why has my new-build shower seal failed already?
A new house dries and settles for a year or two, and sealant is often applied quickly onto dusty surfaces. Both lead to early failure.
Is the work guaranteed?
Yes, for a year. If anything is not right with the work within the year, let us know and we’ll sort it.
Do you work for hotels and businesses?
Yes. We’ve worked for hotels, offices and other businesses and we are fully insured.
Is it worth resealing while the house is still settling?
For failed seals that let water through, the best time is now. Cosmetic gaps can wait until the first year or two of movement has passed.
How we quote for new build mastic
Call for a quick quote. The main things that affect it are:
- How much there is to do
- Working hours on commercial sites
- Mould in or behind the old joints
- Which sealant suits the joint
The cost depends on how much there is to do, how much old material has to come out and access to the work. We give a clear quote before any work starts.
Helping us quote
When you call or email, it’s useful to know:
- What’s wrong with the joints now
- Any previous sealing or DIY work
- Where the job is, and your postcode
- Pictures of the joints, sent by email
Asking for a quote is easy: tell us what needs doing and where, and roughly how big it is. Photos by email help us understand the job.
For landlords and businesses
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance that we can handle for you.
For anyone letting property in or around Lowford, jobs at different addresses can go on one quote. Send us the addresses and the work at each.
What we do, step by step
A visit follows a simple pattern: we look at the joints together, protect the area around them, do the work and clear up. It generally takes a few hours in a single home. In a smaller place like Lowford, parking is seldom the issue; lanes, gates and long drives are worth mentioning. For outside work, side access and the height of the joints help us plan.
- First we work through your snagging list or plot schedule with you.
- Failed or untidy sealant is cut out completely.
- Each joint is cleaned of dust and grit, then primed if required.
- A sealant chosen for each area goes in and is tooled smooth.
- Finally, each room is checked and you are given the cure time.
Before we arrive
- Move anything stored near the joints
- Let us know about stairs, lifts or work at height
- Let us know if you’ve seen damp or leaks

How the job changes by surface
Skirting and floors
As timber and screed dry, skirting and floors shift. Caulk cracks; a flexible sealant moves with it painted or coloured to suit.
Kitchens
Sink joints are wet all the time. A kitchen sealant goes in there, food-safe where it’s needed.
Why deal with it now?
A failed shower or bath seal in a new home lets water into floors and walls that are still drying out. Resealing promptly protects the new finishes around it. In an older home around Lowford, damp from a failed joint can get into timber and plaster, which is far harder to put right than the sealant itself.
Commercial jobs are quoted on the same basis as homes: the amount of work, how we reach it and what it needs, along with when we can work on site. Ask us for a quote and we will go through it with you.

Looking after it afterwards
Good habits help new joints last longer. A few tips:
- Get a leaking seal dealt with straight away
- Don’t seal over failed sealant yourself
- Follow the cure time we give you
- Watch for new gaps as the house dries out
Follow the cure time we give you before the area gets wet. Most silicones need around a day to cure enough for use.
A failed seal in a new home lets water into joists, plasterboard and ceilings. Early resealing keeps the job small.
Joints and finishes in Lowford homes
Lowford is close to the coast. Plot mastic on new homes near the coast takes more weather than it would inland, so it’s worth checking at snagging. The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
If you’ve bought a new home near Bursledon station, the sealant around baths, showers and frames is worth checking in the first year or two.
