New build mastic in Brook Street, done properly
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 since hurried prep is behind a lot of new-build failures. Typical jobs include sealant work across a run of new homes and untidy sealant flagged on a snagging list, across bathrooms & en suites, skirting & floors and windows & doors.
Older homes in small places like Brook Street often have timber floors that move with the seasons, which is why skirting and threshold joints need a flexible sealant, not filler.
A 12-month guarantee comes as standard, so you’re covered after we have gone.

New homes and floors in Brook Street

How to look after the new joints
A little care helps the new joints last. We recommend:
- Wipe joints with warm soapy water
- Put sealant faults on your snagging list early
- Do not seal over failed sealant yourself
- Look at the sealant regularly in the first couple of years
Leave the sealant for the cure time we give you before showering or bathing. Silicone is usually left for about a day to cure enough for use.
If a shower tray or bath seal splits in the first year, look for movement. Have it resealed, and the tray or bath checked, before it gets worse.
What we do, step by step
We bring everything the job needs with us. Once we have agreed what’s being done, the area is protected and the work begins. Most jobs take a few hours in a single home. In a small place like Brook Street, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- Every bit of the old builder’s sealant is cut out down to clean surfaces.
- We clean out the dust and grit left from the build.
- Primer goes on where the surface and product need it, then the new sealant.
- We tool every joint neatly and tell you when each area can be used.
Getting ready for the visit
- Plan for the work area to be out of bounds to pets and children
- Mention any tricky access
- Tell us about any previous sealing or DIY attempts

FAQs for Brook Street
Is Brook Street within the area you cover?
Yes. Brook Street is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Do you work for landlords with property near Haywards Heath station?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. Just phone 0345 464 0079 or drop us an email with the address and what needs doing, and we will send you a clear quote.
Do you use white or clear sealant?
White and clear are the most common, but sealant comes in other colours too. We match the colour to the finish.
Should I go to my builder first?
Start with the builder if you’re in the snagging or warranty period. Once that is done, or if they will not put it right, we will cut it out and reseal it.
Is the work guaranteed?
Yes: twelve months. If anything isn’t right with the work within the year, let us know and we’ll sort it.
Can you work on commercial sites?
Yes. We work in offices, washrooms, hotels and other commercial premises. Working times can be discussed when we quote.
Will you just run a new bead over the existing one?
No. We always remove the existing bead, the joint cleaned and primed where needed, and a new bead applied.
What information do you need?
Only a few details: where it is, what you’ve noticed and how we reach it. Then ring 0345 464 0079 or send us an email.

What affects the cost of new build mastic
Every job gets its own quote. These are the things that affect it:
- Any working-time requirements on site
- The number of rooms or windows
- The type of sealant required
- Access and height
Every job is a little different, so each one gets its own quote. Size, access and the product the joint needs all make a difference.
Asking for a quote
Photos by email are helpful but not essential. Please mention:
- Access, such as stairs, a lift or height
- The problem you’ve noticed
- The address or postcode of the job
- A few pictures by email, if you can
There’s no standard price list, because every job is different. Instead, we give you a clear quote for your job. To get started, call 0345 464 0079 or email us.
Why deal with it now?
It often makes sense to do all the sealant items on a snagging list together. You get one visit and one clear quote. Older cottages and farmhouses around Brook Street can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Combining jobs into one visit normally makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. You’ll get one clear quote for the whole job.

In and around Brook Street, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.
