Common problems we fix in Longparish
The first winter with the heating on dries a new home quickly. Skirting, frames and worktops pull away slightly and cracks appear in the sealant.
Keep an eye out for these signs:
- Plot mastic for developers ahead of handover
- Leaking shower tray seals in a new home
- Gaps opening as the house dries out and settles
- Messy sealant that spoils new finishes
For new homes near Whitchurch (Hampshire) station, it’s worth checking the sealant early, while snags are still fresh.

New build mastic in Longparish, done properly
Building dust is behind a lot of failed new-build sealant. Each joint is cleaned of dust and primed where the product calls for it, so the sealant actually sticks instead of bonding to the dust. We work on bathrooms & en suites, skirting & floors and show homes, and common reasons people get in touch are cracked caulk along new skirting and kitchen sealant that has pulled off the wall.
Around Longparish, older homes often have timber floors that move through the year, which is why skirting and threshold joints need a flexible sealant, not filler.
Every job comes with a one-year guarantee, wherever you are in Hampshire.

The process
A visit follows a simple pattern: we check the joints, protect the area around them, do the work and tidy away. Most jobs take anything from a few hours to several days, depending on the number of plots. In a small place like Longparish, access is generally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- First we work through your snagging list or plot schedule with you.
- The old bead comes out in full, with no layer left behind.
- We clean off dust from the build and prime the surfaces where the product needs it.
- A sealant chosen for each area goes in and is tooled smooth.
- We check every joint and tell you how long each needs to cure.
Preparing for the visit
- Tell us if parking is tricky
- Let us know about earlier repairs to the joints
- Let us know about stairs, lifts or work at height

Advice
When something else is needed
Honest advice matters more to us than a booking, so here’s what new sealant will not do:
- Cracked trays, tiles or worktops
- Leaking fittings rather than failed sealant
- A tray or bath that is not properly supported, until it’s fixed
If you are not sure, just ring 0345 464 0079 or email us and we will give you a straight answer.

Can I do it myself?
If you’ve already had a go yourself, that’s fine. We cut it out and start again.
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
Your questions about new build mastic in Longparish
Do you work for landlords with property near Whitchurch (Hampshire) station?
Yes, we work for landlords and letting agents. Just call 0345 464 0079 or drop us an email and tell us about the property, and we’ll give you a clear quote.
Do you cover Longparish for new build mastic?
Yes. We work across London and the South East, and Longparish is part of that. Just phone 0345 464 0079 or send us an email with a few details of the job.
Why has my new-build shower seal failed already?
A new house dries and settles for a year or two, and sealant is often rushed onto dusty, unprimed surfaces. Either can make it fail early.
Is there any odour?
It depends on the product. Some products have a noticeable smell, others very little, and any smell fades as they cure.
Which products do you use?
Quality sealants from brands including Arbo and Everbuild, picked for each joint. We’ll tell you what we’re using and why.
Are you insured?
Yes. Mr Mastic is fully insured, and we have been doing sealant work for more than 20 years.
Do you do commercial work?
Yes. Hotels, offices and other businesses use us and we are fully insured.
Is the work guaranteed?
Yes. All our work carries our one-year guarantee.
What happens if it’s left?
DIY kits do not solve the main problems with new-build sealant: dust, no primer and old sealant left in the joint. Cutting out, cleaning and priming are what make the difference. In a small place like Longparish, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
No two jobs are quite the same, 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.

- 20+ years of sealant experience
