The Warren New Build Mastic
We cover The Warren for plot mastic for developers and snagging failed sealant in new homes. Old sealant removed completely, joints prepared properly.
- Gaps opening as the house dries out and settles
- Leaking shower tray seals in a new home
- Frame joints opening as the plaster dries
How we handle new build mastic in The Warren
For builders and developers, we work through plots to the schedule you give us. Bathrooms, en suites, kitchens, frames and skirting are sealed ready for handover using the right product for each joint. We are often asked to deal with cracked caulk along new skirting and sealant work across a run of new homes, across plot handovers, windows & doors and bathrooms & en suites.
Where new homes go up in smaller places like The Warren, it’s often a small development or a single plot. Each still needs its sealant and floor joints finished properly from day one.
Big or small, it’s backed by our one-year guarantee.

What sealant work cannot fix
Sealant isn’t the answer to every problem, and we’d rather say so up front. Sealant will not put right:
- Leaks from pipes, valves or wastes, which need a plumber
- Cracked trays, tiles or worktops
- Your warranty claim itself, which is between you and the builder
If in doubt, ring 0345 464 0079 or send us an email and we’ll say what we think before you book.
Joints and surfaces we work on

Quotes for new build mastic in The Warren
You’ll get a clear quote before we start. It’s based on:
- Mould in or behind the old joints
- Any working-time requirements on site
- How much old sealant there is and how hard it is to remove
- The product the joint needs
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’ll explain the quote if you ask.
Helping us quote
Before you ask for a quote, have a think about:
- What’s wrong with the joints now
- Whether it’s a home or a business
- Photos by email, if that’s easy
- How we’d reach the joints
Call for a quick quote, or send an email if you’d rather. Describe what needs sealing and we will explain what’s involved before giving you a price.
Should I try it myself first?
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
What the job involves on each surface
Plot handovers
Developers can send the plot schedule and specification for a quote. We seal bathrooms, kitchens, frames and floors to the agreed spec.
Bathrooms and en suites
En suite showers are a common source of leaks into the room below. A proper reseal keeps water in the tray.
How it works
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. Typically it takes a few hours for most snagging lists, longer for a run of plots. A visit to The Warren is planned like any other: the time, the access and where to park are agreed in advance. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- We start by going through the snagging items or plot schedule with you.
- The failed sealant is removed completely.
- We clean out the dust and grit left from the build.
- 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
- Keep children and pets away from the work area
- Clear the area around the work
- Tell us about any previous sealing or DIY attempts

Advice

Keeping the joints in good condition
A little care helps the new joints last. Our advice:
- Keep pictures and emails about snagging items
- Wait for the cure time before using a resealed shower
- Report sealant problems to your builder during the snagging period
- Get a leaking seal dealt with right away
Do not stand on the bath edge or the lip of the tray in the first few weeks. If a bath or tray moves when you stand in it, get it looked at.
If a shower tray or bath seal splits in the first year, look for movement. Getting it resealed properly, and any movement checked, stops it recurring.

What new build mastic looks like in The Warren

The Warren is part of Bracknell, one of the post-war new towns. Bracknell has kept growing, with newer neighbourhoods added to the original town. Older homes need their sealant and floor joints renewing, newer ones checking at snagging.
