What affects the quote in Henhurst
We do not publish a price list, because no two jobs are the same. What we look at:
- How much old sealant there is and how hard it is to remove
- Working hours on commercial sites
- The size of the job
- Mould in or behind the old joints
There are no prices on our website, because the cost depends so much on the job itself. Call for a quick quote and we’ll talk you through it.

The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:

- How we’d reach the joints
- Any previous sealing or DIY work
If you are in Henhurst and need new build mastic, phone 0345 464 0079 or email us. Tell us what the problem is and where, and we will agree the price before any work begins.
New build mastic in Henhurst
We work in new homes and on new-build sites across Henhurst. One shower or a whole phase of plots, the method doesn’t change: remove, clean, prime where needed, then a neat new bead. We are often asked to deal with cracked sealant around new window and door frames and beads laid onto grit and dust from the build, on bathrooms & en suites, kitchens and show homes.
For a small place like Henhurst, the journey and access are planned in advance, and the work itself is the same as on any site.
The work is guaranteed for twelve months. If something is not right with it in that time, tell us and we will put it right.

Henhurst: your questions answered
I let a flat near Sole Street station. Can you help?
Yes, we work for letting agents and landlords. Just ring 0345 464 0079 or drop us an email and tell us about the property, and we’ll give you a clear price.
Do you cover Henhurst for new build mastic?
Yes. We work across London and the South East, and Henhurst is part of that. Just call 0345 464 0079 or drop us an email with a few details of the job, and we’ll send you a clear quote.
Are you an approved applicator?
Yes. We hold ARBOMaster approved applicator status.
What information do you need?
Just the basics: where it is, what you’ve noticed and how we reach it. After that, simply call 0345 464 0079 or send us an email.
Can you reseal over the builder’s sealant?
No. Over-sealing traps mould and water and soon fails. We remove every bit of the old bead before resealing.
Where are you based?
We’re based in Crawley, West Sussex, and we cover South East England, London and all of Scotland.
Are you fully insured?
Yes. Full insurance covers our work.
What colour sealant will you use?
We use white, clear or a colour to suit the finishes. Let us know your preference when you ask for a quote.
What we can’t put right
To be straight with you, some problems need a different trade:
- Leaking fittings rather than failed sealant
- Baths and trays that move too much for sealant to cope with
- Deciding who is responsible under a builder’s warranty
If you are not sure, just phone 0345 464 0079 or drop us an email and we will give you a straight answer before you book.
What we seal
- Windows & doors
- Skirting & floors
- Bathrooms & en suites
- Kitchens
- Show homes
- Plot handovers

Leave it or put it right?

The cost reflects the work involved, not a rough estimate. That is why we ask a few questions first and agree the price before starting.

What we are called out for in Henhurst
If plaster or screed was still damp when it was sealed, the bond suffers. Site programmes do not always leave time for joints to dry first.
Any of these means the joints need attention:
- Gaps behind new kitchen upstands
- Second-fix sealing on new plots
- Gaps opening as the house dries out and settles
- New-build shower sealant that has already split
For new homes near Sole Street station, it’s worth checking the sealant early, while snags are still fresh.
Questions to ask before you book
- What preparation is included
- What the cure time is
- Whether they seal over old material or remove it
- Whether VAT is included
What happens on the day
When we arrive, we look over the joints with you first, so you know exactly what we are doing. We protect the surfaces around the joints before work begins. The work usually takes a few hours for most snagging lists, longer for a run of plots. Somewhere like Henhurst needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- 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.
- Each bead is tooled and the cure times explained.
How to prepare

Keeping the joints in good condition
Good habits help new joints last longer. A few tips:
- Look at the sealant regularly in the first couple of years
- Don’t wait for the house to settle if water is getting through
- Keep pictures and emails about snagging items
- Put sealant faults on your snagging list early
Keep pictures of the joints and any snagging correspondence with your builder. It helps if anything else comes up during the warranty period.
A failed seal in a new home lets water into joists, plasterboard and ceilings. Catching it early keeps the fix to the sealant and the new finishes intact.
