New build mastic in Aldershot
Failed shower seals, gaps along the skirting and messy beads are common items on a new-home snagging list. If you’re still within the builder’s snagging or warranty period, tell them first and if that stalls, we can do it. We work on kitchens, bathrooms & en suites and skirting & floors, and the jobs we see most are cracks appearing as a new home settles and sealant that never bonded to the surface.
In a town like Aldershot, skirting and floor joints open up as homes settle and floors move with the seasons. A flexible sealant, rather than rigid filler, keeps those joints closed.
A one-year guarantee comes as standard.

Failed sealant is one of the commonest items on a check-out report, and it’s quick to put right between tenancies. Several properties can be quoted together.
Common problems we fix in Aldershot
On many sites, sealant goes on in the final rush before handover. Dusty, unprimed joints are common, and the sealant sits on grit instead of the surface.
The problems people normally mention when they call are:
- Skirting joints opening in the first winter
- Kitchen sealant that has pulled off the wall
- New-build shower sealant that has already split
- Joints pulling apart as timber shrinks
If you’ve bought a new home near Aldershot station, the sealant around baths, showers and frames is worth checking in the first year or two.
What your quote should include
- How the surfaces are prepared before sealing
- When the joint can take water or movement
- Is VAT in the price?
- The length of the guarantee
What affects the cost of new build mastic
There’s no set price list, because jobs vary so much. The quote depends on:
- Whether the work is at height
- Which sealant suits the joint
- Whether there’s mould to deal with
- When we can work, for business premises
Doing several joints on one visit is usually more efficient than separate visits, so it’s worth mentioning everything you’d like done. You’ll get one clear quote for the whole job.
Asking for a quote
The more you tell us, the more accurate the quote. When you ask for a quote, tell us:
- If someone has resealed it before
- Whether it’s a home or a business
- Pictures of the joints, sent by email
- What the problem is, such as mould, gaps, leaks or cracking
Asking for a quote is easy: let us know what needs doing and where, and roughly how big it is. Photos by email help us understand the job, and we’ll come back to you with a quote.
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 chosen for how the joint moves and where it is, then guaranteed for a year.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
Aldershot questions
Is Aldershot in your area for new build mastic?
Yes. Our work covers London and the South East, and Aldershot is part of that. You can ring 0345 464 0079 or drop us an email and let us know what needs doing, and we’ll give you a clear price.
Is there a guarantee on new build mastic in Aldershot?
All our work, in Aldershot and everywhere else, comes with a 12-month guarantee. We are also fully insured and ARBOMaster approved.
When is the best time to reseal in a new build?
It depends on whether water is getting through. A leaking shower or bath seal should be redone straight away, while small cosmetic gaps can wait a while.
Can landlords and businesses book you?
Yes. We work for householders, landlords, letting agents, businesses and hotels.
Do you work through snagging lists?
Yes. Send the list and a few pictures of the sealant items and we’ll give you a quote. We’ll flag anything that needs another trade.
Why has my new-build shower seal failed already?
Cracking in the first couple of years is common as timber and plaster dry out. Poor preparation at handover adds to it.
What information do you need?
Just the basics: where it is, what you’ve noticed and how we reach it. Then phone 0345 464 0079 or drop us an email.
Are you fully insured?
Yes. Mr Mastic is fully insured.
How it works
We bring everything the job needs with us, so there’s nothing for you to buy. After a quick look at the joints together, the area is protected and the work begins. Most jobs take a few hours in a single home.

- We remove the failed sealant and clean the joints.
- We make sure the joints are dry and prime them if needed.
- New sealant goes in, with baths filled first so they’re at their heaviest.
- We check every joint and leave you with the cure times.
Before we arrive
- Let us know if you’ve seen damp or leaks
- Tell us about any previous sealing or DIY attempts
- Keep pets and children clear of the area while we work

Advice
Why it’s worth doing now in Aldershot
Resealing everything on a snagging list in one visit is normally simpler than chasing joints one at a time. It’s one visit, one quote and one set of cure times. Draughts from a gap round a frame, damp under a sill or water behind a bath panel all start small, and early is when they’re cheapest and quickest to sort.
What you pay reflects the work, not a rough estimate. That is why we ask about the job first and give you a clear price before any work starts.
What you get with us
- Full insurance on every job
- We never seal over old sealant
- Anti-fungal silicone where joints get wet
- An ARBOMaster approved applicator
