New build mastic for homes and businesses in Brook
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. In both, preparation makes the difference, because that’s what rushed new-build sealant normally lacks. We work on windows & doors, plot handovers and skirting & floors, and common reasons people get in touch are internal frame sealant that has split and messy sealant that spoils new finishes.
Work in a small place like Brook just needs the journey and access planning, and once on site, the job is the same as anywhere.
There’s a 12-month guarantee on every job.

Different surfaces, different methods
Bathrooms and en suites
En suite showers are a common source of leaks into the room below. Resealing properly keeps water where it belongs.
Show homes
Tired or marked sealant in a show home can be renewed. We cut it out and reseal neatly.
What sealant work can’t fix
Some problems need a builder, plumber or other trade rather than us:
- Plumbing faults behind the sealant
- Baths and trays that move too much for sealant to cope with
- Your warranty claim itself, which is between you and the builder
If in doubt, call 0345 464 0079 or email us and we’ll say what we think before booking.

What affects the quote in Brook
The price is agreed before any work begins. It takes into account:
- The product the joint needs
- How easy the joints are to reach
- The number of rooms or windows
- Mould in or behind the old joints
What it costs depends on how much there is to do, how much old material has to come out and access to the work. We give a clear quote before any work starts, so you know where you stand.
Helping us quote
There’s no need for technical detail. It helps if you can tell us:
- A few photos by email, if you can
- Where the property is
- The problem you’ve noticed
- How many joints, rooms or windows are involved

Do you need new build mastic in Brook?
Fresh sealant can be knocked or cut by trades finishing off. If it’s disturbed before curing, the joint can be left weak.
Look out for these signs:
- Second-fix sealing on new plots
- Messy sealant that spoils new finishes
- New-build shower sealant that has already split
- Skirting joints opening in the first winter
If you’ve bought a new home near Ashurst New Forest station, the sealant around baths, showers and frames is worth checking in the first year or two.

Landlord and commercial work in Brook
If you manage several properties in or around Brook, jobs at different addresses can go on one quote. Send us the addresses and the work at each, and pictures by email help.
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance that we can handle for you.
Looking after it afterwards
Good habits help new joints last longer. Our tips:
- Get a leaking seal dealt with right away
- Ventilate bathrooms well, especially in the first year
- Check bath and shower seals every few months as the house settles
- Put sealant faults on your snagging list early
Do not stand on the bath edge or the lip of the tray. Report any movement in a bath or tray.
Mould takes hold quickly in sealant that has gaps or lifted edges. Resealing before mould gets in saves a harder job later.

What happens on the day
When we get to you, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. After that, the work takes a few hours in a single home. Somewhere as small as Brook, 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.
- Old sealant is cut out and the joints cleaned.
- Joints are dried and primed where the product calls for it.
- 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.
Preparing for the visit
- Mention any tricky access
- Clear items away from the joints we are working on
- Keep children and pets away from the work area

Advice
Questions from Brook
Is Brook in your area for new build mastic?
Yes, Brook is within the area we cover. We work across London and the South East. Just ring 0345 464 0079 or email us with a few details of the job.
Do you cover smaller places like Brook?
Yes. Brook is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Will you just run a new bead over the existing one?
No. Over-sealing traps mould and water and soon fails. All the old sealant comes out before work begins.
Which products do you use?
We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice, and we will explain our choice.
What information do you need?
A short description and the location. We will ask anything else we need to know.
Do you guarantee your work?
Yes, for a year. If anything isn’t right with the work within the year, let us know and we’ll sort it.
Can I do it myself?
Sometimes. Preparation is everything: all the old sealant out, and a clean, dry joint. We can always put it right if it fails.
Do you take on second-fix sealing for builders?
Yes. Plot mastic and second-fix sealing for developers is part of our work. Send us the plot schedule and we will quote.
