Leave it or put it right?
Small cosmetic gaps can wait for the house to settle, but water getting through can’t. Not sure whether yours can wait? You can phone 0345 464 0079 or drop us an email with a few photos and we will tell you. Where a wall is exposed, as many are in small places like Keeper's Corner, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
The cost depends on the size of the job, how hard the old material is to remove and access to the work. You will have a clear quote before any work starts, so you know where you stand.

About our new build mastic in Keeper's Corner
Our new-build work comes in two parts: plot mastic for developers, and putting right failed sealant for people who’ve bought a new home. Both get the same care over preparation, because that is what rushed new-build sealant usually lacks. We work on bathrooms & en suites, kitchens and plot handovers, and the jobs we see most are messy sealant that spoils new finishes and skirting joints opening in the first winter.
Work in a small place like Keeper's Corner just needs the journey and access planning, and the work itself is the same as on any site.
We stand behind the work with a 12-month guarantee.

What new build mastic looks like in Keeper's Corner

Surface by surface
Kitchens
Worktops in new homes can move slightly as the house dries, which opens gaps along the back. We reseal them with a flexible sealant.
Skirting and floors
Where the floor meets a bath panel or kitchen plinth, the joint keeps mop water out. They get a flexible, water-resistant sealant.
DIY versus a professional finish
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
For landlords and businesses
Letting agents and landlords in Keeper's Corner can book us as well as householders. Sealant work between tenants keeps a property looking cared for.

What happens on the day
A visit follows a simple pattern: we check the joints, protect the area around them, do the work and tidy away. Most jobs take a few hours for most snagging lists, longer for a run of plots. Somewhere as small as Keeper's Corner, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We look at why each joint failed, including any movement.
- We remove the failed sealant and clean the joints.
- We make sure the joints are dry and prime them if needed.
- Baths are filled with water, then the new sealant is applied.
- The finished joints are checked and the cure times given.
Preparing for the visit
- Let us know if you’ve seen damp or leaks
- Let us know about stairs, lifts or work at height
- Keep pets and children clear of the area while we work

How to look after the new joints
Joint life depends on how it’s used and looked after. We suggest:
- Watch for new gaps as the house dries out
- Keep photos and emails about snagging items
- Ventilate bathrooms well, especially in the first year
- Resist patching a failed seal with a tube from the DIY shop
Keep the bathroom ventilated, especially in the first year. Run the fan or open a window after bathing.
The sooner you deal with untidy or cracking sealant, the less there is to put right. Small faults turn into leaks if left.
What affects the quote in Keeper's Corner
Some jobs are bigger than they look, and some smaller. What affects the quote:
- Whether old sealant or filler has to be cut out
- The number and length of the joints
- How many rooms, windows or areas are involved
- Whether the work is at height
No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all make a difference, and we will explain the quote if you ask.
What to tell us for a quote
There’s no need for technical detail. It helps if you can tell us:
- What the problem is, such as mould, gaps, leaks or cracking
- If it’s domestic, commercial or a hotel
- If someone has resealed it before
- A few photos by email, if you can
There’s no standard price list. Instead, we send you a clear quote for your job. To arrange one, phone 0345 464 0079 or email us.
