New build mastic in Eastrop, done properly
Building dust is behind a lot of failed new-build sealant. We clean every joint thoroughly and prime where the surface and product need it, so the sealant actually sticks. We work on skirting & floors, windows & doors and kitchens, and common reasons people get in touch are kitchen sealant that has pulled off the wall and joints pulling apart as timber shrinks.
Homes around Eastrop 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.
You get a 12-month guarantee, the same in Eastrop as everywhere else we work.

How we quote for new build mastic
The price is agreed before any work begins. It’s based on:
- How many rooms, windows or areas are involved
- When we can work, for business premises
- Mould in or behind the old joints
- How easy the joints are to reach
No two jobs are quite the same, so we quote each one individually. 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
You don’t need to know the technical terms. It helps if you can tell us:
- What’s wrong with the joints now
- How we’d reach the joints
- Photos by email, if that is easy
- The type of property
Asking for a quote is easy: let us know what needs doing and where and its rough size. A few pictures by email make the job easier to understand, and we will take it from there.

Landlords, agents and businesses in Eastrop
Failed sealant is one of the commonest items on a check-out report, and it’s easy to sort out between tenants. We can quote for more than one property at once.
Whether it’s one flat or a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a 12-month guarantee.
Looking after it afterwards
Simple care keeps the joints in good condition. We recommend:
- Keep water off fresh sealant until it has cured
- Use the extractor fan every time you shower
- Avoid running a DIY bead over the old one
- Don’t wait for the house to settle if water is getting through
Keep an eye on the joints over the first couple of years. Small gaps can appear as the house dries and can be resealed later.
Early snagging is easier snagging. Left alone, a small crack can become a leak in a busy bathroom.
Surface by surface
Windows and doors
On new builds, external frame sealant can be patchy. We reseal it with a weatherproof, flexible sealant.
Kitchens
Worktops in new homes can move slightly as the house dries, which opens gaps along the back. A fresh flexible bead closes them.
What we do, step by step
Before we leave, we go over the finished joints with you and tell you how long to leave it. The visit itself usually takes anything from a few hours to several days, depending on the number of plots, depending on the amount of work. A visit to Eastrop is planned like any other: the time, the access and where to park are agreed in advance. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- The failed sealant is removed completely down to clean surfaces.
- Joints are vacuumed and cleaned of building dust.
- Primer goes on where the surface and product need it, then the new sealant.
- Each bead is tooled and the cure times explained.
Getting ready for the visit
- Let us know about earlier repairs to the joints
- For business premises, tell us about site rules or sign-in
- Tell us if parking is tricky

Advice
Leave it or put it right?
A failed shower or bath seal in a new home lets water into floors and walls that are still drying out. Dealing with it early keeps the damage away from ceilings, floors and finishes. In an older home around Eastrop, damp from a failed joint can get into timber and plaster, which is far harder to put right than the sealant itself.
Doing several joints on one visit is usually more efficient than separate visits. We’ll send you a clear quote for the lot.

Yes. Hotels, offices and other businesses use us.
Do the sealants smell?
There can be a smell while the sealant cures. Opening a window helps.
Is it worth resealing while the house is still settling?
Where water is getting through, do not wait. Hairline cosmetic gaps can wait until the house has settled.

Is it worth trying it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
