About our new build mastic in Penton Grafton
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. Typical jobs include frame joints opening as the plaster dries and leaking shower tray seals in a new home, across show homes, plot handovers and skirting & floors.
For a small place like Penton Grafton, the journey and access are planned in advance, and once on site, the job is the same as anywhere.
Whatever the size of the job, you get the same one-year guarantee.

Work for landlords, hotels and businesses
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance.
Whether it’s one flat or a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a 12-month guarantee.
What sealant work can’t fix
We’d rather tell you now than do work that will not last, so here’s what sealant cannot put right:
- Cracking that points to a structural problem
- Deciding who is responsible under a builder’s warranty
- A tray or bath that isn’t properly supported, until it’s fixed
Not sure which it is? You can call 0345 464 0079 or send us an email and we’ll tell you honestly.

What we are called out for in Penton Grafton
A new house holds a lot of water from the build, and it dries out over the first couple of years. As it does, timber shrinks and joints open, and sealant that cannot keep up splits.
The problems people normally mention when they call are:
- Cracked sealant around new window and door frames
- Cracks appearing as a new home settles
- Sealant applied over dusty or wet surfaces
- Leaking shower tray seals in a new home
If you’ve bought a new home near Andover station, the sealant around baths, showers and frames is worth checking in the first year or two.
Questions to ask before booking
- Whether they seal over old material or remove it
- When the joint can take water or movement
- What the quote includes, VAT included or not
- Which colour the sealant will be
Penton Grafton: your questions answered
Do you cover smaller places like Penton Grafton?
Yes, smaller places are covered as well as towns. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Do you work for landlords with property near Andover station?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. Just ring 0345 464 0079 or drop us an email with the address and what needs doing, and we’ll give you a clear price.
Is it messy?
Tidy work is part of the job. Nearby surfaces are protected.
What do you need from me for a quote?
Only a few details: where it is, what you’ve noticed and how we reach it. After that, simply ring 0345 464 0079 or email us.
Do you do commercial work?
Yes, regularly. We can plan bigger jobs in stages to suit the site.
Do you work for developers?
Yes. We take on second-fix sealant work across new plots. We clean and prime joints properly to keep callbacks down.
Are you ARBOMaster approved?
Yes. Mr Mastic is an ARBOMaster approved applicator and we’re fully insured too.
Should I wait before resealing?
Where water is getting through, do not wait. Small gaps that are just cosmetic can be resealed once movement has slowed.
DIY sealant or a professional job?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
Different surfaces, different methods
Bathrooms and en suites
En suite seals are easy to miss on a snagging list until they leak. A proper reseal keeps water in the tray.
Skirting and floors
Wet-area floor joints need a flexible seal. They get a flexible, water-resistant sealant.
What happens if it’s left?
A failed shower or bath seal in a new home lets water into floors and walls that are still drying out. Resealing promptly protects the new finishes around it. Where a wall is exposed, as many are in small places like Penton Grafton, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
There are no prices on our website, because the cost depends so much on the job itself. Call for a quick quote and we will talk you through it.

How it works
Once we’re on site, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. Most jobs then take a few hours for most snagging lists, longer for a run of plots. Somewhere like Penton Grafton needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- The failed sealant is removed completely, with no layer left behind.
- Joints are vacuumed and cleaned of building dust.
- We prime where needed and apply a sealant suited to each joint.
- We tool every joint neatly and tell you when each area can be used.
How to prepare
- Keep children and pets away from the work area
- Try not to wet indoor joints just before the visit
- Tell us about any water getting in
