New build mastic in Shalcombe
A new house keeps drying out and settling for its first couple of years. Timber shrinks, plaster dries and baths and trays bed down, so sealant that was laid quickly before handover often cracks. We work on windows & doors, show homes and bathrooms & en suites, and common reasons people get in touch are leaking shower tray seals in a new home and internal frame sealant that has split.
For a small place like Shalcombe, the journey and access are planned in advance, and once on site, the job is the same as anywhere.
Each job carries a 12-month guarantee, large or small.

What the job involves on each surface
Plot handovers
Send us the schedule and any sealant specification for a quote. Sealant work across the plot is covered to the agreed spec.
Kitchens
Beside the sink, the joint takes water every day. A kitchen sealant goes in there, food-safe where it’s needed.
What sealant work cannot fix
It helps to know what we can’t do too:
- Your warranty claim itself, which is between you and the builder
- Leaks from pipes, valves or wastes, which need a plumber
- Structural cracks in walls or ceilings
Not sure which it is? You can call 0345 464 0079 or send us an email and we’ll tell you honestly before booking.

Joints and finishes in Shalcombe homes
Shalcombe is close to the coast. New homes near the sea put their outside mastic to work from day one, so it’s worth checking at snagging. Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
In and around Shalcombe, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint. Whether the job is in Shalcombe itself or nearby, the right material for each joint matters as much as a neat finish.

Shalcombe: your questions answered
Is new build mastic in Shalcombe guaranteed?
Every job comes with our one-year guarantee, wherever it is. We’re also fully insured and ARBOMaster approved.
Is Shalcombe in your area for new build mastic?
Yes, Shalcombe is within the area we cover. We work across London and the South East. Just ring 0345 464 0079 or email us with a few details of the job, and we will give you a clear price.
Are you insured?
Yes. We are fully insured, and we have been doing sealant work for more than 20 years.
Why does sealant fail so quickly in new builds?
There are normally two causes: the house moving as it dries, and sealant that never bonded properly. Cutting it out and resealing properly fixes both.
I’m a tenant. Can you help?
Of course. Check with your landlord; we can send the quote to them too.
Where is Mr Mastic based?
Our base is in Crawley, and we cover South East England, London and all of Scotland.
How long will you be here?
That depends on the amount of work, but as a guide it takes anything from a few hours to several days, depending on the number of plots. We will tell you when we quote.
Can new sealant go on top of the old bead?
No. We always remove the existing bead, then clean and prime the joint, before resealing.
How the visit works
We keep the work tidy and contained to the joints we’re treating, so you can carry on as normal. The job generally takes anything from a few hours to several days, depending on the number of plots. In a small place like Shalcombe, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We look at why each joint failed, including any movement.
- We remove the failed sealant and clean the joints.
- We make sure the joints are dry and prime them if needed.
- New sealant goes in, with baths filled first so they’re at their heaviest.
- The finished joints are checked and the cure times given.
Getting ready for the visit
- Mention any tricky access
- Where the joints are inside, avoid wetting them before we arrive
- Move anything stored near the joints

What affects the quote in Shalcombe
There’s no set price list, because jobs vary so much. The quote depends on:
- Working hours on commercial sites
- How many areas need sealing
- Whether the work is at height
- The number and length of the joints
Leaving a failed joint usually makes the job bigger, not smaller, because water and mould keep working on it. If you are unsure, phone 0345 464 0079 or drop us an email and we’ll give you an honest view and a quote.
Helping us quote
To help us quote quickly, please include:
- The address or postcode of the job
- Whether it’s a home or a business
- How many joints, rooms or windows are involved
- If someone has resealed it before

Can I do it myself?
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
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 does not work out, we can still put it right.
Aftercare tips
Aftercare is simple:
- Wipe joints with warm soapy water
- Keep pictures and emails about snagging items
- Keep water off fresh sealant until it has cured
- Get a leaking seal dealt with right away
Leave the sealant for the cure time we give you before showering or bathing. Silicone is usually left for about a day to cure enough for use.
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 in a busy bathroom.
