Boyatt Wood New Build Mastic
Our applicators work in Boyatt Wood on plot mastic for developers and snagging failed sealant in new homes. Old sealant removed completely, joints prepared properly and every job guaranteed for a year.
- Joints pulling apart as timber shrinks
- Cracked caulk along new skirting
- Messy sealant that spoils new finishes
Aftercare tips
So the new joints stay in good condition:
- Open a window or run the fan after bathing
- Wipe joints with warm soapy water
- Act quickly if a seal starts to leak
- Report sealant problems to your builder during the snagging period
Leave the sealant for the cure time we give you before showering or bathing. Most silicones need around a day to cure enough for use.
Lifting sealant traps moisture and mould behind it. Dealing with it before it goes black saves a harder job later.
About our new build mastic in Boyatt Wood
Some new-home owners let the house settle before resealing. That makes sense for small gaps that are just cosmetic, but a failed shower or bath seal shouldn’t wait. If you are dealing with second-fix sealing on new plots and worktop and upstand sealant coming away, we can put it right.
In and around Boyatt Wood, floors range from older timber boards to tiles and newer finishes, from timber that moves with the seasons to tiles laid on concrete. Skirting and threshold joints need a sealant that suits the floor.
Each job carries a 12-month guarantee.

When it isn’t the sealant
Sealant is not the answer to every problem, and we’d rather say so up front. It will not solve:
- Movement caused by a poorly fitted tray or bath
- Cracking that points to a structural problem
- Your warranty claim itself, which is between you and the builder
If you’re not sure, just ring 0345 464 0079 or email us and we will give you a straight answer.
Surfaces we seal
- Plot handovers
- Bathrooms & en suites
- Kitchens
- Show homes
- Windows & doors
- Skirting & floors
Common questions in Boyatt Wood
Can you help a landlord with a rental near Eastleigh station?
Yes, we work for landlords and letting agents. You can call 0345 464 0079 or drop us an email with the address and a few details, and we’ll give you a fixed price before we start.
Is Boyatt Wood within the area you cover?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Do I have to be there?
We need access to the joints, so we’ll agree that with you when we book. For inside work, that normally means someone being in.
What should I tell you?
Where the job is, what the problem is and roughly how big it is. If you can, email a few pictures.
Who should fix failed sealant in a new build?
Start with your builder while their snagging or warranty period runs. After that, or if their repair keeps failing, we can do it and our work is guaranteed for a year.
Do you work for developers?
Yes. Plot mastic and second-fix sealing for developers is part of our work. Send the schedule and any specification and we will give you a quote.
How much does new build mastic cost in Boyatt Wood?
Size, access and the old material all affect the cost. Call for a quick quote and we will talk you through it.

What affects the cost of new build mastic
Jobs vary more than people expect. What affects the quote:
- How much old sealant there is and how hard it is to remove
- Mould in or behind the old joints
- Access and height
- Which sealant suits the joint
Instead of a standard rate, we look at what your job involves: how many joints, what’s in them now and how we reach them. You’ll know the price before we begin.
Helping us quote
When you call or email, these details help:
- Pictures of the joints, sent by email
- The type of property
- Where the property is
- Access, such as stairs, a lift or height

- The failed sealant is removed completely, with no layer left behind.
- Joints are vacuumed and cleaned of building dust.
- We prime where needed and apply a sealant suited to each joint.
- Each bead is tooled and the cure times explained.

It’s worth asking for a quote if you see:
- Plot mastic for developers ahead of handover
- Messy sealant that spoils new finishes
- Shower seals failing in the first year or two
- Skirting joints opening in the first winter
