What new build mastic looks like in Little Waltham
Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you’ve bought a new home near Beaulieu Park station, the sealant around baths, showers and frames is worth checking in the first year or two.

New build mastic for homes and businesses in Little Waltham
We work in new homes and on new-build sites across Little Waltham. 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. If you’re dealing with worktop and upstand sealant coming away and gaps opening as the house dries out and settles, we can help.
Older homes in small places like Little Waltham often have timber floors that move with the seasons, so skirting and threshold joints need a flexible sealant rather than a rigid filler.
All our work is covered by a one-year guarantee, wherever you are in Essex.

What we’re called out for in Little Waltham
A new house holds a lot of water from the build, which takes a year or two to dry out. Drying timber shrinks and pulls joints apart and the sealant has to cope with the movement.
People generally contact us when they notice something like this:
- Frame joints opening as the plaster dries
- New-build shower sealant that has already split
- Gaps opening as the house dries out and settles
- Sealant work across a run of new homes
In and around Little Waltham, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

Landlord and commercial work in Little Waltham
Hotels need rooms back in use, so we plan the work room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.
Whether it’s one flat or a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a one-year guarantee.
Leave it or put it right?
DIY kits don’t solve the main problems with new-build sealant: grit, unprimed surfaces and old layers underneath. Cutting out, cleaning and priming are what make the difference. Around Little Waltham, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all play a part, and we will explain the quote if you ask.
What you get with us
- More than 20 years in sealant work
- Sealant colour chosen to suit
- Fully insured

Little Waltham: your questions answered
Will you come out to Little Waltham?
Yes, Little Waltham is covered. Our work covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Is Little Waltham in your area for new build mastic?
Yes. We work across London and the South East, and Little Waltham is part of that. You can call 0345 464 0079 or drop us an email and let us know what needs doing.
Is it normal for sealant to crack in a new home?
Cracking in the first couple of years is common as timber and plaster dry out. Rushed application on dusty surfaces makes it worse.
Do I need to be at home?
Access is agreed with you when the job is booked. Indoors, that generally means someone at home.
Do the sealants smell?
Possibly a little. It fades as the sealant cures, and ventilation helps.
Do you guarantee your work?
Yes. Each job is guaranteed for twelve months, wherever you are.
Should I try DIY first?
Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Can you work from my snagging list?
Yes. Send us the sealant items on the list, with pictures if you can and we will give you a quote. We’ll tell you if anything on it isn’t a sealant job.

What else we do in Little Waltham
How it works
When we get to you, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. After that, the work takes a few hours in a single home. In a small place like Little Waltham, access is generally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- The failed sealant is removed completely down to clean surfaces.
- Joints are vacuumed and cleaned of building dust.
- We prime where needed and apply a sealant suited to each joint.
- We tool every joint neatly and tell you when each area can be used.
How to prepare
- Where the joints are inside, avoid wetting them before we arrive
- On commercial sites, let us know about site rules
- Tell us about any water getting in

Keeping the joints in good condition
After the cure time, these simple habits help:
- Photograph failed sealant before it’s redone
- Wait for the cure time before using a resealed shower
- Put sealant faults on your snagging list early
- Avoid scourers and strong chemicals on sealant
Keep photos of the joints and any snagging correspondence with your builder. It’s useful if you need to raise other issues later.
Lifting sealant traps moisture and mould behind it. Dealing with it before it goes black keeps the job straightforward.
What affects the quote in Little Waltham
The quote reflects the job in front of us. We look at:
- The number and length of the joints
- How easy the joints are to reach
- Mould in or behind the old joints
- How many rooms, windows or areas are involved
Rather than a set price list, we look at what your job involves: how many joints, what’s in them now and how we reach them. You will know the price before we begin.
What to tell us for a quote
When you contact us, it’s useful to know:
- Where the job is, and your postcode
- Pictures of the joints, sent by email
- What’s wrong with the joints now
- Any previous sealing or DIY work
Call for a quick quote, or send an email if you’d rather. Tell us about the joints that need doing and we’ll explain what’s involved.
Surface by surface
Skirting and floors
Where the floor meets a bath panel or kitchen plinth, the joint keeps mop water out. They get a flexible, water-resistant sealant.
Kitchens
Worktops in new homes can move slightly as the house dries, opening gaps behind the upstand. We reseal them with a flexible sealant.
