About our new build mastic in Hempstead
Our new-build work comes in two parts: plot mastic for developers, and putting right failed sealant for people who’ve bought a new home. In both, preparation makes the difference, because that’s what rushed new-build sealant normally lacks. We work on skirting & floors, plot handovers and bathrooms & en suites, and common reasons people get in touch are untidy sealant flagged on a snagging list and frame joints opening as the plaster dries.
In smaller places like Hempstead, new homes tend to come as small developments or single plots. Each still needs its sealant and floor joints finished properly from day one.
Your job is guaranteed for a year, as with all our work.

Common problems we fix in Hempstead
Fresh sealant can be knocked or cut by trades finishing off. A bead disturbed before it has cured may never seal properly.
People generally contact us after spotting something like this:
- Cracks appearing as a new home settles
- Cracked sealant around new window and door frames
- New-build shower sealant that has already split
- Skirting joints opening in the first winter
For new homes near Rainham (Kent) station, it’s worth checking the sealant early, while snags are still fresh.

What else we do in Hempstead
What affects the quote in Hempstead
Your quote is based on your job. We take into account:
- Mould in or behind the old joints
- The product the joint needs
- How many areas need sealing
- Any working-time requirements on site
Doing several joints on one visit generally makes better use of the time than several visits. You will get one clear quote for the whole job.
What to tell us for a quote
A few details help us give you an accurate quote. When you get in contact, it helps to mention:
- Where the job is, and your postcode
- Any access issues, like height or stairs
- A few photos by email, if you can
- If someone has resealed it before

Can I do it myself?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
How to look after the new joints
Joint life depends on how it’s used and looked after. We suggest:
- Watch for new gaps as the house dries out
- Avoid scourers and strong chemicals on sealant
- Put sealant faults on your snagging list early
- Don’t wait for the house to settle if water is getting through
Ventilation matters in a new home, which is still drying out. Use the extractor fan or open a window after showers so moisture does not sit on the sealant.
The sooner you deal with untidy or cracking sealant, the less there is to put right. Left alone, a small crack can become a leak over time.
Hempstead questions
Can you help a landlord with a rental near Rainham (Kent) station?
Yes, we work for landlords and letting agents. Just call 0345 464 0079 or email us and tell us about the property, and we will give you a clear price.
Will you come out to Hempstead?
Yes, we do. 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.
Are you ARBOMaster approved?
Yes. We are an ARBOMaster approved applicator, the approved applicator scheme for Arbo sealants.
Should I go to my builder first?
Start with the builder if you are in the snagging or warranty period. If it isn’t resolved, we can reseal it properly.
Can you match the sealant colour to my new kitchen or bathroom?
It depends on the joint: white or clear for most sanitary joints, colours for worktops, floors and frames. We agree the colour before work begins.
Do you do commercial work?
Yes, regularly. We can plan bigger jobs in stages to suit the site.
Are you fully insured?
Yes. Full insurance covers our work.
Will there be a smell?
Some sealants have a smell while they cure, but it fades. Ventilation helps.
What happens on the day
Once we’re on site, we check the joints match what you told us. If anything is different, we explain it before carrying on. After that, the work takes a few hours for most snagging lists, longer for a run of plots. A visit to Hempstead is planned like any other: the time, the access and where to park are agreed in advance. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- We start by going through the snagging items or plot schedule with you.
- The failed sealant is removed completely, with no layer left behind.
- We clean out the dust and grit left from the build.
- Primer goes on where the surface and product need it, then the new sealant.
- We tool every joint neatly and tell you when each area can be used.
Before we arrive
- Keep pets and children clear of the area while we work
- Where the joints are inside, avoid wetting them before we arrive
- Tell us about access, such as stairs, a lift or high-level joints

When it is not the sealant
Honest advice matters more to us than a booking, so here’s what sealant can’t fix:
- Movement caused by a poorly fitted tray or bath
- Leaking fittings rather than failed sealant
- Deciding who is responsible under a builder’s warranty
Not sure which it is? You can call 0345 464 0079 or drop us an email and we will tell you honestly.

New homes and floors in Hempstead
Hempstead is within about 3 miles of the coast. Plot mastic on new homes near the coast takes more weather than it would inland, so any gaps are best picked up early. London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
