About our new build mastic in Ellingham
For builders and developers, we work through plots to the schedule you give us. We seal bathrooms, kitchens, windows, doors and skirting so plots are ready to hand over. We work on plot handovers, skirting & floors and bathrooms & en suites, and common reasons people get in touch are smeared, uneven beads picked up at snagging and shower seals failing in the first year or two.
Work in a small place like Ellingham just needs the journey and access planning, and once on site, the job is the same as anywhere.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

What new build mastic looks like in Ellingham
Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
In and around Ellingham, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

Common problems we fix in Ellingham
Baths and trays settle under load once the home is lived in. A bath sealed empty drops slightly when filled, straining the joint and can tear.
Look out for any of the following:
- Sealant that never bonded to the surface
- Worktop and upstand sealant coming away
- Messy sealant that spoils new finishes
- Internal frame sealant that has split
For jobs in and around Ellingham, choosing the right material for each joint is as important as a tidy finish.

What we cannot put right
We’ll always be straight with you, so here’s what new sealant won’t do:
- Disputes or warranty claims with your builder
- A tray or bath that isn’t properly supported, until it’s fixed
- Settlement cracks that need a surveyor
If in doubt, ring 0345 464 0079 or drop us an email and we’ll say what we think before you book.

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.
We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.
Can I do it myself?
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so just mention it when you contact us.
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
How we quote for new build mastic
Every job gets its own quote. This is what makes a difference:
- Which sealant suits the joint
- How many rooms, windows or areas are involved
- How much old sealant there is and how hard it is to remove
- When we can work, for business premises
Leaving a failed joint generally makes the job bigger, not smaller. If you’re not sure whether it needs doing, ring 0345 464 0079 or drop us an email and we’ll give you an honest view and a quote.
Helping us quote
A few details help us give you an accurate quote. When you ask for a quote, tell us:
- The address or postcode of the job
- The problem you’ve noticed
- Access, such as stairs, a lift or height
- Whether it has been sealed before
It all starts with a short chat. Describe the problem, the location and the size of the job. Whenever you’re ready, ring 0345 464 0079 or send us an email.
The process
We bring everything the job needs with us. After a quick look at the joints together, we protect the area and start. Most jobs take anything from a few hours to several days, depending on the number of plots. Somewhere like Ellingham needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- 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.
- Baths are filled with water, then the new sealant is applied.
- We check every joint and leave you with the cure times.
How to prepare
- Mention any sign-in or site rules at work premises
- Let us know about parking restrictions
- Where the joints are inside, avoid wetting them before we arrive

Related advice
Why deal with it now?
A tube of sealant from the DIY shop will not fix the cause: grit, unprimed surfaces and old layers underneath. Proper removal and preparation are what make it last. Where a wall is exposed, as many are in small places like Ellingham, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.

What does new build mastic cost?
There’s no set price, as it 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.
What should I tell you?
A short description and the location, plus pictures if you have them. If we need more, we will ask.
Can you work from my snagging list?
Yes. Send the list and a few pictures of the sealant items and we will give you a quote. We will flag anything that needs another trade.
Is it worth trying it myself?
Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Who should fix failed sealant in a new build?
If you are still within the builder’s snagging or warranty period, report it to them first. If they’re slow or the fix doesn’t last, we can help.
I rent my home. Can I book you?
Yes, though it’s best to check with your landlord first. Many landlords are glad to have it sorted.
