- New-build shower sealant that has already split
Different surfaces, different methods
Plot handovers
We work through plots to your schedule, sealing each room ready for handover. Joints are prepared properly before sealing.
Windows and doors
A draught at a new window can be a missed or failed joint. We check and reseal the frame edges.
How we handle new build mastic in Banstead
Snagging sealant properly means taking the failed bead out completely. Fresh silicone can’t bond to the old layer, so it all comes out before we clean, dry and reseal. We work on windows & doors, skirting & floors and bathrooms & en suites, and the jobs we see most are skirting joints opening in the first winter and worktop and upstand sealant coming away.
Homes around Banstead range from older cottages to newer houses, and their floors range just as widely, from timber that moves with the seasons to tiles laid on concrete. The sealant at skirtings and thresholds has to suit the floor it meets.
Big or small, you get the same 12-month guarantee.

Signs you need new build mastic in Banstead
On many sites, sealant goes on in the final rush before handover. Dusty, unprimed joints are common, so the bead never bonds properly.
People usually contact us after spotting something like this:
- Internal frame sealant that has split
- Plot mastic for developers ahead of handover
- Gaps opening as the house dries out and settles
- Messy sealant that spoils new finishes
If you’ve bought a new home near Banstead station, the sealant around baths, showers and frames is worth checking in the first year or two.

What does new build mastic cost?
There’s no set price, as it 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.

Do you guarantee your work?

Can you match the sealant colour to my new kitchen or bathroom?

When is the sealant fully cured?
Most sealants are touch-dry well before they’re fully cured. We will give you the cure time for the product we used before we leave.
Do I have to be there?
For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.
What affects the quote in Banstead
Your quote is based on your job. We look at:
- Working hours on commercial sites
- Mould in or behind the old joints
- The number and length of the joints
- Whether the work is at height
Combining jobs into one visit is generally more efficient than separate visits, so tell us about everything that needs sealing. We will give you a clear quote for the lot.
What we need to know
To make quoting easier, please include:
- The problem you’ve noticed
- Roughly how big the job is
- Pictures of the joints, sent by email
- If it’s domestic, commercial or a hotel
We do not publish a price list, because every job is different. Instead, your job gets its own clear quote. To arrange one, call 0345 464 0079 or drop us an email.
When it is not the sealant
We’d rather tell you now than do work that will not last, so these are the limits:
- Cracking that points to a structural problem
- A tray or bath that is not properly supported, until it’s fixed
- Deciding who is responsible under a builder’s warranty
If you are not sure, just call 0345 464 0079 or send us an email and we will give you a straight answer.

How the visit works
We keep the work tidy and contained to the area we’re working on, so you can get on with your day. Expect the work to take anything from a few hours to several days, depending on the number of plots, and we tell you how long to leave it before we go. Parking around Banstead is generally easier than in a town centre, but mention any lanes, gates or long drives. For outside work, side access and the height of the joints help us plan.
- We start by going through the snagging items or plot schedule with you.
- Every bit of the old builder’s sealant is cut out.
- Joints are vacuumed and cleaned of building dust.
- We prime where needed and apply a sealant suited to each joint.
- We tool every joint neatly and tell you when each area can be used.
How to prepare
- Tell us about access, such as stairs, a lift or high-level joints
- Plan for the work area to be out of bounds to pets and children
- Where the joints are inside, avoid wetting them before we arrive

Why act early in Banstead
DIY kits do not solve the main problems with new-build sealant: grit, unprimed surfaces and old layers underneath. Proper removal and preparation are what make it last. Homes in smaller places like Banstead can face more weather, and failed outside joints let damp into walls. Indoors, a failed seal lets water into floors and panels as it would anywhere.
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed. Call for a quick quote and we’ll explain what it covers.
Why Banstead customers choose us
- A 12-month guarantee on all work
- We leave the area clean and tidy
- White, clear, grey or another colour, product permitting
- We never seal over old sealant
See our cost guide and our reviews.
Looking after it afterwards
So the new joints stay in good condition:
- Wipe joints with warm soapy water
- Report sealant problems to your builder during the snagging period
- Ventilate bathrooms well, especially in the first year
- Get a leaking seal dealt with straight away
Ventilation matters in a new home, which is still drying out. Use the extractor fan or open a window after showers.
Don’t let the snagging period run out with sealant problems unreported. After that, putting it right may fall to you so report it promptly.
