Work for landlords, hotels and businesses
Whether it’s one flat or a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance that we can handle for you.
New build mastic in North Aston
We carry out plot mastic and second-fix sealing for builders, and snagging reseals for new-home owners. In both, preparation makes the difference. We work on show homes, bathrooms & en suites and plot handovers, and people most often call us about cracked sealant around new window and door frames and skirting joints opening in the first winter.
Somewhere as small as North Aston, new homes tend to be conversions, self-builds or a few houses rather than an estate. Every one needs its sealant and floor joints done properly, whatever the size of the site.
All of our work is guaranteed for twelve months, in North Aston and everywhere else we cover.

Aftercare tips
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Open a window or run the fan after bathing
- Check bath and shower seals every few months as the house settles
- Get a leaking seal dealt with right away
- Avoid running a DIY bead over the old one
Leave the sealant for the cure time we give you before showering or bathing. Silicone is usually left for about a day.
Report failed sealant to the builder while you are in the snagging period. Once it ends, the repair may be down to you, so raise it early.

What new build mastic looks like in North Aston
Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.

What we do, step by step
All our tools and materials come with us in the van, so there’s nothing for you to buy. Once we have agreed what’s being done, the area is protected and the work begins. It normally takes a few hours for most snagging lists, longer for a run of plots. In a small place like North Aston, access is usually the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We start by agreeing which joints are on the list, from the snagging sheet or plot schedule.
- The old bead comes out in full, with no layer left behind.
- Each joint is cleaned of dust and grit, then primed if required.
- We apply a sealant that suits each joint and tool it to a neat finish.
- Finally, each room is checked and you’re given the cure time.
How to prepare
- Clear items away from the joints we are working on
- Mention if the joints have been sealed before
- Let us know about parking restrictions

North Aston questions
Do you work for landlords with property near Heyford station?
Yes, rental work is part of what we do. You can call 0345 464 0079 or drop us an email with the address and a few details, and we’ll give you a fixed price before work begins.
Will you come out to North Aston?
Yes, North Aston is covered. We work across London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
What do you put in the joint?
We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference, and we’ll explain our choice.
Do you use white or clear sealant?
The colour is chosen to suit the tiles, worktop or frame. Let us know your preference when you ask for a quote.
How long does new build mastic take?
Typically it takes a few hours in a single home. Larger jobs naturally take longer, and we’ll say how long yours will take.
Is it worth resealing while the house is still settling?
That depends on the joint. Failed seals in wet areas need doing now, but cosmetic gaps can wait for movement to slow.
Do I have to be there?
If the work is inside, we need someone to let us in. After that, you can carry on with your day.
Is it worth trying it myself?
It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.
How the job changes by surface
Windows and doors
Draughts around new frames are often a sealant gap. We look at the joints and reseal where needed.
Show homes
We can refresh show-home sealant that has discoloured or been knocked. The old bead comes out and a clean new one goes in.
Signs you need new build mastic in North Aston
A new house holds a lot of water from the build, and it dries out over the first couple of years. Drying timber shrinks and pulls joints apart and the sealant has to cope with the movement.
These are the problems we’re asked about most:
- Messy sealant that spoils new finishes
- Plot mastic for developers ahead of handover
- Frame joints opening as the plaster dries
- Skirting joints opening in the first winter
In and around North Aston, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

Why deal with it now?
A tube of sealant from the DIY shop won’t fix the cause: grit, unprimed surfaces and old layers underneath. Proper removal and preparation are what make it last. Older cottages and farmhouses around North Aston can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Combining jobs into one visit normally makes better use of the time than several visits, so tell us about everything that needs sealing. We will send you a clear quote for the lot.
