Your questions about new build mastic in Fairford Leys
Do you cover smaller places like Fairford Leys?
Yes, we do. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
I let a flat near Aylesbury station. Can you help?
Yes, we work for landlords and agents. You can phone 0345 464 0079 or drop us an email with the address and a few details, and we’ll give you a fixed price before we start.
Does someone need to be in?
For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.
What does new build mastic cost?
We do not publish prices, because the cost depends on the job: how much there is, what’s there now, how we reach it and what it needs. We agree the price before any work begins.
Which products do you use?
Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference, and we will explain our choice.
Can I send you my snagging list?
Yes. Send it with pictures and we will quote for the sealant items. If something isn’t sealant, we will say so.
Can new sealant go on top of the old bead?
No. Fresh silicone doesn’t stick to the old layer, so it soon lifts and traps water. The old sealant always comes out first.
When is the best time to reseal in a new build?
Any seal that’s leaking should be redone right away. For small cosmetic gaps, waiting until the house has settled can save doing them twice.
New build mastic for homes and businesses in Fairford Leys
Across Fairford Leys, we work for both new-home owners and the builders handing those homes over. One shower or a whole phase of plots, the method does not change: remove, clean, prime where needed, then a neat new bead. If you’re dealing with smeared, uneven beads picked up at snagging and frame joints opening as the plaster dries, we can put it right, on bathrooms & en suites, plot handovers and windows & doors alike.
In smaller places like Fairford Leys, new homes tend to come as small developments or single plots. Each still needs its sealant and floor joints finished properly from day one.
All our work is covered by our one-year guarantee.

When to call us in Fairford Leys
Not every new-build joint gets the right sealant: decorators’ caulk in a wet area, or a stiff sealant where there’s movement. Neither lasts long.
Any of these means the joints need attention:
- Messy sealant that spoils new finishes
- Second-fix sealing on new plots
- Sealant that never bonded to the surface
- Kitchen sealant that has pulled off the wall
For new homes near Aylesbury station, it’s worth checking the sealant early, while snags are still fresh.

Can I do it myself?
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.

How it works
On the day, there’s very little for you to do. Show us the job and we will take it from there. The work itself takes a few hours for most snagging lists, longer for a run of plots. For a job in Fairford Leys, we agree the time, the access and parking before the day. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- First we work through your snagging list or plot schedule with you.
- The old bead comes out in full, with no layer left behind.
- Surfaces are cleaned of building dust and primed where needed.
- A sealant chosen for each area goes in and is tooled smooth.
- Finally, each room is checked and you are given the cure time.
Preparing for the visit
- For business premises, tell us about site rules or sign-in
- Clear items away from the joints we are working on
- Keep children and pets away from the work area

Related advice
Why it’s worth doing now in Fairford Leys
Resealing everything on a snagging list in one visit is generally simpler than chasing joints one at a time. You get one visit and one clear quote. Homes in smaller places like Fairford Leys can face more weather, and failed outside joints let damp into walls. Inside, a split seal lets water into floors and panels just as it would anywhere.
Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether the work is at height. We take all of that into account in your quote.

Aftercare tips
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Ventilate bathrooms well, especially in the first year
- Look at the sealant regularly in the first couple of years
- Get a leaking seal dealt with right away
- Avoid running a DIY bead over the old one
Follow the cure time we give you before the area gets wet. Silicone is generally left for about a day to cure enough for use.
The sooner you deal with untidy or cracking sealant, the less there is to put right. Left alone, a small crack can become a leak.
