Somerton questions
Do you cover Somerton for new build mastic?
Yes, Somerton is within the area we cover. We work across London and the South East. You can call 0345 464 0079 or send us an email and tell us what needs doing.
Will you come out to Somerton?
Yes. Somerton is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Can I do it myself?
That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.
How long before the joint can be used?
Most sealants are touch-dry well before they’re fully cured. We’ll give you the cure time for the product we used before we leave.
Do you guarantee your work?
Yes. Every job comes with a one-year guarantee.
Where do you work from?
Our base is Crawley. Our area covers South East England, London and Scotland.
What do you need from me for a quote?
A short description and the location. If we need more, we will ask.
Will you just run a new bead over the existing one?
No. The old sealant is cut out fully, the joint cleaned and primed where needed, before resealing.
New build mastic for homes and businesses in Somerton
A new build should have a neat, sound bead at every joint. Smeared, patchy or cracked sealant is worth sorting early, before water reaches anything behind it. We’re often asked to deal with frame joints opening as the plaster dries and gaps behind new kitchen upstands, on bathrooms & en suites, windows & doors and show homes.
Work in a small place like Somerton just needs the journey and access planning, and once on site, the job is the same as anywhere.
There’s a 12-month guarantee on every job, whatever its size.

How to look after the new joints
After the cure time, these simple habits help:
- Wipe joints with warm soapy water
- Follow the cure time we give you
- Report sealant problems to your builder during the snagging period
- Do not wait for the house to settle if water is getting through
Photograph failed sealant before it’s redone and keep the builder’s replies. It’s useful if you need to raise other issues later.
A seal that splits early is often a sign of movement. Have it resealed, and the tray or bath checked, before it gets worse.
Leave it or put it right?
If you’re still in the builder’s snagging or warranty period, ask them to put it right first. If it keeps failing or isn’t dealt with, we can reseal it properly. Where a wall is exposed, as many are in small places like Somerton, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.

What affects the cost of new build mastic
We do not publish a price list, because jobs vary so much. What we look at:
- How much old sealant there is and how hard it is to remove
- The amount of work
- Any mould that needs treating
- How many rooms, windows or areas are involved
Doing several joints on one visit is usually more efficient than separate visits, so tell us about everything that needs sealing. You will get one clear quote for the whole job.
What to tell us for a quote
When you call or email, these details help:
- A few photos by email, if you can
- If it’s domestic, commercial or a hotel
- Any access issues, like height or stairs
- If someone has resealed it before
We quote each job on its own, so start by telling us what you need. Simply phone 0345 464 0079 or drop us an email and describe the job, and photos are welcome.
What sealant work can’t fix
We won’t take on work that will not last, so here’s what sealant can’t put right:
- A tray or bath that isn’t properly supported, until it’s fixed
- Disputes or warranty claims with your builder
- Broken tiles or a split tray
If you’re not sure, just call 0345 464 0079 or send us an email and we’ll give you a straight answer.

Skirting and floors
Floors and skirting move as the house dries and the heating runs. Caulk cracks; a flexible sealant moves with it in a colour to suit.
Show homes
Bathrooms, kitchens and frames in show homes are sealed or resealed to a neat finish. Tell us when the home is open so we can plan around it.

It usually takes a few hours for most snagging lists, longer for a run of plots. Somewhere as small as Somerton, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We start by going through the snagging items or plot schedule with you.
- Every bit of the old builder’s sealant is cut out.
- 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.
Getting ready for the visit
- Keep pets and children clear of the area while we work
- Clear the area around the work
