New build mastic for homes and businesses in Shirrell Heath
For builders and developers, we work through plots to the schedule you give us. Bathrooms, en suites, kitchens, frames and skirting are sealed ready for handover using the right product for each joint. Common call-outs are for sealant that never bonded to the surface and internal frame sealant that has split, on show homes, bathrooms & en suites and skirting & floors.
In a village or hamlet like Shirrell Heath, 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.
Big or small, it’s backed by our 12-month guarantee in Shirrell Heath and across Hampshire.

Surface by surface
Bathrooms and en suites
En suite showers are a common source of leaks into the room below. A proper reseal keeps water in the tray.
Show homes
We seal show-home bathrooms, kitchens and frames to a tidy standard. We’ll plan around viewing times.
What we can’t put right
Some problems need a builder, plumber or other trade rather than us:
- Cracking that points to a structural problem
- Baths and trays that move too much for sealant to cope with
- Cracked trays, tiles or worktops
Not sure which it is? You can ring 0345 464 0079 or drop us an email and we’ll tell you honestly before you book.

What happens on the day
Most of a good job is in the preparation, and we do not rush it. Every joint is cleaned and dried before new material goes in. In total, it usually takes a few hours in a single home. For a village or hamlet like Shirrell Heath, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- We start by going through the snagging items or plot schedule with you.
- Every bit of the old builder’s sealant is cut out 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
- Let us know about stairs, lifts or work at height
- For indoor joints, keep the area dry beforehand if you can
- Mention if the joints have been sealed before

DIY versus a professional finish
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Aftercare tips
Looking after new joints is easy, and it makes a real difference:
- Put sealant faults on your snagging list early
- Clean sealant with mild detergent, not abrasives
- Wait for the cure time before using a resealed shower
- Do not seal over failed sealant yourself
Keep pictures of the joints and any snagging correspondence with your builder. It’s useful if you need to raise other issues later.
Report failed sealant to the builder while you are in the snagging period. After that, putting it right may fall to you so report it promptly.
FAQs for Shirrell Heath
I let a flat near Botley station. Can you help?
Yes, rental work is part of what we do. You can phone 0345 464 0079 or drop us an email with the address and a few details, and we will give you a fixed price before any work starts.
Is Shirrell Heath within the area you cover?
Yes, Shirrell Heath is covered. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Do the sealants smell?
Sometimes, a little. It fades as the sealant cures, and ventilation helps.
What sealant do you use?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.
Can I do it myself?
It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.
Can you match the sealant colour to my new kitchen or bathroom?
The colour is chosen to suit the tiles, worktop or frame. Tell us what you’d like when you get a quote.
Is it normal for sealant to crack in a new home?
Lots of new homes see sealant crack early, because the house is drying and settling. Poor preparation at handover adds to it.
Will you leave a mess?
We keep the work tidy. Nearby surfaces are protected, and we clear up when we are done.
Do you need new build mastic in Shirrell Heath?
Baths and trays settle under load once the home is lived in. A bath sealed empty drops slightly when filled, straining the joint and can tear.
Keep an eye out for these signs:
- Sealant work across a run of new homes
- Cracked sealant around new window and door frames
- Kitchen sealant that has pulled off the wall
- Cracked caulk along new skirting
If you’ve bought a new home near Botley station, the sealant around baths, showers and frames is worth checking in the first year or two.
