Questions from Penton Mewsey
Can you help a landlord with a rental near Andover station?
Yes, we work for landlords and agents. You can ring 0345 464 0079 or send us an email with the address and a few details, and we’ll give you a fixed price before work begins.
Do you cover smaller places like Penton Mewsey?
Yes. Penton Mewsey is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Is it worth resealing while the house is still settling?
It depends on whether water is getting through. A leaking shower or bath seal should be redone right away, but cosmetic gaps can wait for movement to slow.
Will it make a mess?
Tidy work is part of the job. Nearby surfaces are protected, and we clear up when we’re done.
What does new build mastic cost?
There’s no set price, as it depends on the job: its size, the old material, access and the product needed. You’ll get a clear quote before work begins.
Can you do several jobs on one visit?
Yes, and it often makes sense. Combining jobs makes good use of the visit, so mention them when you ask for a quote.
When is the sealant fully cured?
Most sealants are touch-dry well before they’re fully cured. We’ll tell you how long to leave the joint.
Do you hold any approvals?
Yes. We’re ARBOMaster approved, the scheme for applicators of Arbo sealants.
New build mastic for homes and businesses in Penton Mewsey
We carry out plot mastic and second-fix sealing for builders, and snagging reseals for new-home owners. Both get the same care over preparation, because that is what rushed new-build sealant normally lacks. We’re often asked to deal with kitchen sealant that has pulled off the wall and smeared, uneven beads picked up at snagging, across kitchens, skirting & floors and bathrooms & en suites.
In a village or hamlet like Penton Mewsey, 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.
There’s a 12-month guarantee on every job.

What affects the cost of new build mastic
Some jobs are bigger than they look, and some smaller. What affects the quote:
- The number of rooms or windows
- Any mould that needs treating
- Whether old sealant or filler has to be cut out
- The type of sealant required
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed. Call for a quick quote and we’ll go through it with you.
Asking for a quote
Photos help, but a description is a good start. Try to tell us:
- The rough size of the job
- Whether it’s a home or a business
- A few photos by email, if you can
- What’s wrong with the joints now
To get a quote, call 0345 464 0079 or drop us an email and tell us where the job is and what the problem looks like. We’ll give you a clear price before any work starts.
When it is not the sealant
We won’t take on work that won’t last, so these are the limits:
- Leaking fittings rather than failed sealant
- Structural cracks in walls or ceilings
- Broken tiles or a split tray
Not sure which it is? You can call 0345 464 0079 or drop us an email and we’ll tell you honestly before you book.
What we seal
- Bathrooms & en suites
- Kitchens
- Show homes

Common problems we fix in Penton Mewsey
The first winter with the heating on dries a new home quickly. Gaps open along skirting, frames and worktops and cracks appear in the sealant.
Look out for these signs:
- Gaps behind new kitchen upstands
- Gaps opening as the house dries out and settles
- Frame joints opening as the plaster dries
- Gaps between new skirting and floors
For new homes near Andover station, it’s worth checking the sealant early, while snags are still fresh.
Before you book anyone
- What happens if they find a problem under the old sealant
- How long to leave it before use
- Are they insured?
- How the surfaces are prepared before sealing
The process
Before we leave, we go over the finished joints with you and explain the cure time. The visit itself usually takes anything from a few hours to several days, depending on the number of plots, depending on how much there is to do. Somewhere like Penton Mewsey needs a little journey planning: 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 go through the snagging list or plot schedule and agree the joints to do.
- Failed or untidy sealant is cut out completely.
- Surfaces are cleaned of building dust and primed where needed.
- 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.
How to prepare
- On commercial sites, let us know about site rules
- Move anything stored near the joints
- Tell us about any water getting in

Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.
Surface by surface
Skirting and floors
Wet-area floor joints need a flexible seal. We seal them with a sealant suited to wet areas.
Plot handovers
Taking time over preparation reduces return visits. We clean out building dust before sealing and primer used where needed.
Why deal with it now?
A hairline gap at a skirting can wait, but a leaking seal cannot. If you’re unsure which you have, call 0345 464 0079 or send us an email with pictures and we will give you a straight answer. Older cottages and farmhouses around Penton Mewsey can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all play a part.
