New Build Mastic in Aston Abbotts
New-build sealant joints in Aston Abbotts need attention? We cut out the old, prepare the joints and apply the right sealant.
- Gaps opening as the house dries out and settles
- Second-fix sealing on new plots
- Sealant applied over dusty or wet surfaces
What the job involves on each surface
Plot handovers
We work through plots to your schedule, sealing each room ready for handover. Each joint is cleaned and primed where needed so the sealant lasts.
Skirting and floors
Floors and skirting move as the house dries and the heating runs. Caulk cracks; a flexible sealant moves with it.
New build mastic in Aston Abbotts, done properly
We carry out plot mastic and second-fix sealing for builders, and snagging reseals for new-home owners. In both, preparation makes the difference since hurried prep is behind a lot of new-build failures. We’re often asked to deal with gaps opening as the house dries out and settles and smeared, uneven beads picked up at snagging, across show homes, windows & doors and bathrooms & en suites.
Around Aston Abbotts, older homes often have timber floors that move through the year, so skirting and threshold joints need a flexible sealant rather than a rigid filler.
There’s a 12-month guarantee on every job, large or small.

Aston Abbotts questions
Is Aston Abbotts in your area for new build mastic?
Yes, Aston Abbotts is within the area we cover. Our work covers London and the South East. Just call 0345 464 0079 or send us an email with a few details of the job, and we will give you a clear price.
I let a flat near Aylesbury station. Can you help?
Yes, we work for letting agents and landlords. Just call 0345 464 0079 or send us an email and tell us about the property, and we’ll give you a clear quote.
Do you have insurance?
Yes. Mr Mastic is fully insured, with over 20 years’ experience in sealant work.
Can you match the sealant colour to my new kitchen or bathroom?
That depends on what the joint meets: white or clear for most sanitary joints, colours for worktops, floors and frames. We will agree it with you first.
Do the sealants smell?
Possibly a little. Any smell clears as the sealant cures, and ventilation helps.
Will it make a mess?
We keep the work tidy. We protect what’s around the joints, and the area is left clean when we finish.
Why does sealant fail so quickly in new builds?
It’s common, and there are normally two reasons: movement as the house dries and settles, and sealant laid onto dust without primer. Cutting it out and resealing properly fixes both.
Are you an approved applicator?
Yes. We’re an ARBOMaster approved applicator, the approved applicator scheme for Arbo sealants.
What affects the cost of new build mastic
Some jobs are bigger than they look, and some smaller. The main factors:
- The number and length of the joints
- Which sealant suits the joint
- Whether the work is at height
- Mould in or behind the old joints
Doing several joints on one visit is generally more efficient than separate visits, so it’s worth mentioning everything you’d like done. We will give you a clear price for the lot.
Asking for a quote
A few details help us give you an accurate quote. When you get in contact, it helps to mention:
- How many joints, rooms or windows are involved
- What the problem is, such as mould, gaps, leaks or cracking
- Whether it’s a home or a business
- Where the property is

Keep an eye out for any of the following:
- Worktop and upstand sealant coming away
- Sealant that never bonded to the surface
- Plot mastic for developers ahead of handover
- Messy sealant that spoils new finishes
In and around Aston Abbotts, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.
Before booking anyone
- How the colour is chosen
- What product goes in the joint
- Who turns up on the day
- What insurance they hold
Keeping the joints in good condition
Aftercare is simple:
- Keep pictures and emails about snagging items
- Report sealant problems to your builder during the snagging period
- Wait for the cure time before using a resealed shower
- Watch for new gaps as the house dries out
Watch the joints as the house settles. Small gaps can appear as the house dries and can be resealed later.
Leave a failed new-build seal and water can reach the floor and the ceiling below. Early resealing keeps the job small and the new finishes intact.

Should I try it myself first?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
