New build mastic for homes and businesses in Nursling
Developers send us the plot schedule and we work through it. Bathrooms, en suites, kitchens, frames and skirting are sealed ready for handover with a sealant suited to each area. Common call-outs are for shower seals failing in the first year or two and joints pulling apart as timber shrinks, across windows & doors, kitchens and skirting & floors.
If you’ve bought a new home in or near Nursling, the first year or two is a good time to check the sealant. Gaps at skirtings, shower seals pulling away and missing mastic around frames are common snags.
Big or small, you get the same 12-month guarantee in Nursling and across Southampton.

Questions from Nursling
Will you come out to Nursling?
Yes, we do. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
I let a flat near Redbridge station. Can you help?
Yes, rental work is part of what we do. You can call 0345 464 0079 or send us an email with the address and a few details, and we’ll give you a fixed price before any work starts.
Can you work from my snagging list?
Yes. Send the list and a few photos of the sealant items. We will tell you if anything on it is not a sealant job.
Do I need to be at home?
It depends on the job. Inside work needs someone to give us access.
Should I try DIY first?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. If it does not work out, we can redo it.
Why does sealant fail so quickly in new builds?
There are normally two causes: movement as the house dries and settles, and sealant laid onto dust without primer. A proper reseal deals with both.
Where is Mr Mastic based?
Our base is Crawley, with over 20 years’ experience. We work across South East England, London and Scotland.
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.
What we are called out for in Nursling
A new house holds a lot of water from the build, which takes a year or two to dry out. As it does, timber shrinks and joints open.
Keep an eye out for any of the following:
- Messy sealant that spoils new finishes
- Sealant work across a run of new homes
- Beads laid onto grit and dust from the build
- Gaps between new skirting and floors
For new homes near Redbridge station, it’s worth checking the sealant early, while snags are still fresh.

Leave it or put it right?
If you are still in the builder’s snagging or warranty period, ask them to put it right first. If it’s slow, or the same joint keeps failing, a proper reseal from a specialist is the next step. In a smaller place like Nursling, wherever a wall is exposed, a failed outside joint is a real source of damp. Inside, a split seal lets water into floors and panels just as it would anywhere.
Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we’ll explain the quote if you ask.
Why us?
- Colour picked to suit the job
- A choice of colours where the product allows
- ARBOMaster approved applicator
- We leave the area clean and tidy

DIY versus a professional finish
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so just mention it when you contact us.
How it works
Most of a good job is in the preparation, so that’s where we spend the time. Every joint is cleaned and dried before new material goes in. In total, it usually takes a few hours for most snagging lists, longer for a run of plots. For a job in Nursling, we agree the time, the access and parking before the day. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- First we work through your snagging list or plot schedule with you.
- We cut out every bit of the failed or messy sealant.
- Surfaces are cleaned of building dust and primed where needed.
- New sealant suited to each joint is applied and tooled neatly.
- Each area is checked and left with its cure time.
Getting ready for the visit
- For business premises, tell us about site rules or sign-in
- Keep children and pets away from the work area
- Mention any tricky access

How to look after the new joints
How long the joints last depends on use and care. Here’s what we suggest:
- Raise failed sealant with the developer while you are covered
- Wait for the cure time before using a resealed shower
- Watch for new gaps as the house dries out
- Use the extractor fan every time you shower
Photograph failed sealant before it’s redone and keep the builder’s replies. It’s useful if you need to raise other issues later.
Early snagging is easier snagging. Small faults turn into leaks if left over time.
