New build mastic in Knights Enham
Building dust is behind a lot of failed new-build sealant. Each joint is cleaned of dust and primed where the product calls for it, so the sealant actually sticks. We work on kitchens, bathrooms & en suites and plot handovers, and people most often call us about shower seals failing in the first year or two and joints pulling apart as timber shrinks.
Somewhere as small as Knights Enham, 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 as standard, so you’re not left on your own once the job is done.

Knights Enham questions
Do you cover smaller places like Knights Enham?
Yes, Knights Enham is covered. We work across London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Can you help a landlord with a rental near Andover station?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. Just call 0345 464 0079 or email us with the address and what needs doing, and we’ll send you a clear quote.
Do I need to be at home?
For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.
Is the work guaranteed?
Yes, for a year. If anything isn’t right with the work within the year, let us know and we will sort it.
Can you quote for more than one area?
Yes. Just list everything you need.
My new home is still under warranty. Should I contact you?
Your builder, if you’re still in their snagging or warranty period. After that, or if their repair keeps failing, we can do it.
What sealant do you use?
We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice, and we’ll tell you what we’re using.
How long does new build mastic take?
Typically it takes a few hours for most snagging lists, longer for a run of plots. Larger jobs naturally take longer, and we’ll say how long yours will take.
What affects the cost of new build mastic
The price is agreed before any work begins. It’s based on:
- How many areas need sealing
- Which sealant suits the joint
- Whether there’s mould to deal with
- Whether old sealant or filler has to be cut out
Every job is a little different, so each one gets its own quote. Size, access and the product the joint needs all play a part.
Helping us quote
When you contact us, these details help:
- The problem you’ve noticed
- Any access issues, like height or stairs

What we do, step by step

Most jobs then take a few hours for most snagging lists, longer for a run of plots. Somewhere as small as Knights Enham, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- Each joint is checked for movement before work begins.
- Old sealant is cut out and the joints cleaned.
- 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.

Advice
What we cannot put right
New sealant can’t fix everything, and we’d rather say so up front. Sealant won’t put right:
- Leaks from pipes, valves or wastes, which need a plumber
- Structural cracks in walls or ceilings
- Damaged fittings that need replacing
If you’re not sure, just ring 0345 464 0079 or drop us an email and we will give you a straight answer.
Surfaces we seal
- Bathrooms & en suites
- Show homes
- Kitchens
- Plot handovers
- Skirting & floors
- Windows & doors
Keeping the joints in good condition
Looking after new joints is easy:
- Raise failed sealant with the developer while you are covered
- Ventilate bathrooms well, especially in the first year
- Record problems with dated pictures
- Avoid scourers and strong chemicals on sealant
Keep pictures of the joints and any snagging correspondence with your builder. It’s useful if you need to raise other issues later.
Do not let the snagging period run out with sealant problems unreported. Once it ends, the repair may be down to you.

Common problems we fix in Knights Enham
Fresh sealant can be knocked or cut by trades finishing off. If it’s disturbed before curing, the joint can be left weak and it shows once the home is in use.
Look out for these signs:
- Beads laid onto grit and dust from the build
- Cracked sealant around new window and door frames
- Second-fix sealing on new plots
- Smeared, uneven beads picked up at snagging
Around Knights Enham, as everywhere, new build mastic is only as good as the preparation behind it.

What happens if it’s left?
Small cosmetic gaps can wait for the house to settle, but a leaking seal cannot. If you’re unsure which you have, phone 0345 464 0079 or send us an email with pictures and we’ll give you a straight answer. Where a wall is exposed, as many are in small places like Knights Enham, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Leaving a failed joint normally makes the job bigger, not smaller, as water and mould keep getting in. If you are not sure whether it needs doing, call 0345 464 0079 or email us for an honest opinion and a quote.
