New build mastic for homes and businesses in Aylesbury
Snagging sealant properly means taking the failed bead out completely. New silicone won’t bond to old silicone, so it all comes out before we clean, dry and reseal. We work on kitchens, plot handovers and bathrooms & en suites, and people most often call us about sealant that never bonded to the surface and kitchen sealant that has pulled off the wall.
Commercial units around a large town like Aylesbury usually have concrete floors with joints that need filling and resealing as they wear. At home, it’s the same idea on a smaller scale: skirtings, thresholds and shower seals.
Big or small, it’s backed by our 12-month guarantee in Aylesbury and across Buckinghamshire.

Why act early in Aylesbury
It often makes sense to do all the sealant items on a snagging list together. It’s one visit, one quote and one set of cure times for the lot. In flats, shops and offices in Aylesbury, a failed joint can let water into the unit below or behind a wall, where it can go unnoticed until the damage is done.
Homes and businesses are quoted the same way: how much there is to do, how we reach it and what it needs. Call for a quick quote and we will go through it with you.

Work for landlords, hotels and businesses
Hotels need rooms back in use, so we plan the work room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.
Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. Several properties can be quoted together.
Aftercare tips
Aftercare is simple:
- Watch for new gaps as the house dries out
- Raise failed sealant with the developer while you’re covered
- Photograph failed sealant before it’s redone
- Ventilate bathrooms well, especially in the first year
Keep pictures of the joints and any snagging correspondence with your builder. It’s useful if you need to raise other issues later.
A failed seal in a new home lets water into joists, plasterboard and ceilings. Catching it early keeps the fix to the sealant and the new finishes intact.
How it works
We work through the job in order: protection first, then preparation, sealing and a tidy-up. For most jobs that takes a few hours in a single home and we leave things clean and tidy. In central Aylesbury, parking can be tight, so tell us about driveways, permits or nearby car parks. Let us know about stairs, lifts or shared entrances too.
- 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.
- Surfaces are cleaned of building dust and primed where needed.
- A sealant chosen for each area goes in and is tooled smooth.
- Each area is checked and left with its cure time.
Preparing for the visit
- Tell us about any water getting in
- Mention any sign-in or site rules at work premises
- Mention any parking rules near the property

Asking for a quote is easy: let us know what needs doing and where, and roughly how big it is. A few photos by email make the job easier to understand.
Advice
Questions from Aylesbury
I let a flat near Aylesbury station. Can you help?
Yes, rental work is part of what we do. Just call 0345 464 0079 or send us an email and tell us about the property, and we will give you a clear price.
What guarantee comes with new build mastic in Aylesbury?
Every job comes with our one-year guarantee, wherever it is. We’re fully insured, and an ARBOMaster approved applicator.
Can you reseal over the builder’s sealant?
No. Over-sealing traps mould and water and soon fails. All the old sealant comes out before any work starts.
Do you work through snagging lists?
Yes. We often work straight from a snagging list. We will go through the sealant items and agree what we’ll do.
How long does new build mastic take?
As a guide, most jobs take a few hours in a single home. Bigger jobs take longer.
Where is Mr Mastic based?
We are based in Crawley, and we cover South East England, London and all of Scotland.
How long should I leave it?
Many sealants skin over quickly but take longer to cure fully. We will give you the cure time for the product we used.
Will it make a mess?
No. We work neatly, protect the area around the joints and tidy up afterwards.
What we’re called out for in Aylesbury
The wrong product is sometimes used in the wrong place: decorators’ caulk in a wet area, or a stiff sealant where there’s movement. Both fail early.
Look out for these signs:
- Internal frame sealant that has split
- Leaking shower tray seals in a new home
- Untidy sealant flagged on a snagging list
- Sealant applied over dusty or wet surfaces
If you’ve bought a new home near Aylesbury station, the sealant around baths, showers and frames is worth checking in the first year or two.
