About our new build mastic in Sweethaws
Developers send us the plot schedule and we work through it. Bathrooms, en suites, kitchens, frames and skirting are sealed ready for handover using the right product for each joint. We work on windows & doors, plot handovers and bathrooms & en suites, and people most often call us about worktop and upstand sealant coming away and leaking shower tray seals in a new home.
In a village or hamlet like Sweethaws, new homes are more likely to be a barn conversion or a handful of houses than a big estate. Every one needs its sealant and floor joints done properly, whatever the size of the site.
We stand behind the work with a 12-month guarantee, so you’re not left on your own once the job is done.

Landlords, agents and businesses in Sweethaws
From a single let to a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.
In hotels, rooms out of use cost money, so we plan the work room by room. Hotel work is part of what we do, alongside homes and businesses.
What we do, step by step
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. Typically it takes a few hours in a single home, and the area is left clean. Somewhere like Sweethaws 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.
- We start by agreeing which joints are on the list, from the snagging sheet or plot schedule.
- The old bead comes out in full, with no layer left behind.
- Each joint is cleaned of dust and grit, then primed if required.
- We apply a sealant that suits each joint and tool it to a neat finish.
- Each area is checked and left with its cure time.
Getting ready for the visit
- Mention any leaks or damp you’ve noticed
- Tell us about access, such as stairs, a lift or high-level joints
- Mention any parking rules near the property

What affects the quote in Sweethaws
There’s no set price list, because jobs vary so much. What we look at:
- How many areas need sealing
- How easy the joints are to reach
- Whether old sealant or filler has to be cut out
- Whether there’s mould to deal with
Every job is a little different, so each one gets its own quote. Size, access and the product the joint needs all make a difference, and we will explain the quote if you ask.
Asking for a quote
When you contact us, it’s useful to know:
- Photos by email, if that is easy

Sweethaws questions
Do you cover Sweethaws for new build mastic?
Yes, Sweethaws is within the area we cover. We work across London and the South East. Just phone 0345 464 0079 or send us an email with a few details of the job.
Will you come out to Sweethaws?
Yes, Sweethaws is covered. 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.
When is the best time to reseal in a new build?
That depends on the joint. A leaking shower or bath seal should be redone straight away, while small cosmetic gaps can wait a while.
Are you ARBOMaster approved?
Yes. We hold ARBOMaster approved applicator status, and we are fully insured.
Is the work guaranteed?
Yes, for a year. If anything isn’t right with the work within the year, let us know and we will sort it.
Will you leave a mess?
Not at all. We work neatly, protect the area around the joints and tidy up afterwards.
Where are you based?
Our base is in Crawley, West Sussex, and we cover South East England, London and all of Scotland.
Can I do it myself?
You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.
How the job changes by surface
Plot handovers
Good preparation at handover saves snagging later. Dust from the build is removed first and primer used where needed.
Windows and doors
Internal joints between frames and plaster often crack as a new house dries. We remove cracked sealant and apply a flexible one in a matching colour.
Do you need new build mastic in Sweethaws?
New homes are full of moisture from plaster, screed and concrete, and it dries out over the first couple of years. As it does, timber shrinks and joints open and the sealant has to cope with the movement.
Most people get in touch when they notice one of these:
- Smeared, uneven beads picked up at snagging
- New-build shower sealant that has already split
- Cracks appearing as a new home settles
- Cracked sealant around new window and door frames
For new homes near Crowborough station, it’s worth checking the sealant early, while snags are still fresh.
Questions to ask before you book
- Whether VAT is included
- Which sealant they’ll use, and why
- What the cure time is
- Who does the work, and how experienced they are
What sealant work can’t fix
In fairness, there are a few things sealant will not fix:
- Cracking that points to a structural problem
- Damaged fittings that need replacing
- Leaking fittings rather than failed sealant
If in doubt, phone 0345 464 0079 or drop us an email and we will say what we think.
Joints and surfaces we work on
- Kitchens
- Plot handovers
- Bathrooms & en suites
- Show homes
- Windows & doors
- Skirting & floors
Why it’s worth doing now in Sweethaws
A tube of sealant from the DIY shop will not fix the cause: dust, no primer and old sealant left in the joint. Proper removal and preparation are what make it last. Around Sweethaws, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Combining jobs into one visit is usually more efficient than separate visits. We’ll give you a clear price for the lot.
What you get with us
- We never seal over old sealant
- Domestic, commercial and hotel work
- Tidy, careful work
- White, clear, grey or another colour, product permitting
