New build mastic for homes and businesses in Danesfield
We never seal over a failed new-build bead. Fresh silicone can’t bond to the old layer, so the joint is cut out, cleaned, dried and resealed. Common call-outs are for cracks appearing as a new home settles and cracked sealant around new window and door frames, on show homes, windows & doors and bathrooms & en suites.
Somewhere as small as Danesfield, new homes tend to be conversions, self-builds or a few houses rather than an estate. Each still needs its sealant and floor joints finished properly.
We guarantee the work for a year. If something isn’t right with it in that time, tell us and we will put it right.

How we quote for new build mastic
The quote reflects the job in front of us. We look at:
- Which sealant suits the joint
- The old material and how stubborn it is
- Working hours on commercial sites
- The size of the job
A failed joint rarely gets cheaper to fix by waiting. If you are not sure whether it needs doing, call 0345 464 0079 or send us an email and we’ll give you an honest view and a quote.
What to tell us for a quote
The more you tell us, the more accurate the quote. When you ask for a quote, tell us:
- How many joints, rooms or windows are involved
- Whether it has been sealed before
- The type of property
- Where the job is, and your postcode
We quote each job on its own. Just call 0345 464 0079 or send us an email with the details, and pictures are welcome.
Aftercare tips
Good habits help new joints last longer. Our tips:
- Ventilate bathrooms well, especially in the first year
- Clean sealant with mild detergent, not abrasives
- Wait for the cure time before using a resealed shower
- Watch for new gaps as the house dries out
Ventilation matters in a new home, which is still drying out. Run the fan or open a window after bathing so moisture does not sit on the sealant.
Mould takes hold quickly in sealant that has gaps or lifted edges. Resealing before mould gets in saves a harder job later.
Questions from Danesfield
Do you cover Danesfield for new build mastic?
Yes, Danesfield is within the area we cover. Our work covers London and the South East. Just call 0345 464 0079 or drop us an email with a few details of the job, and we will send you a clear quote.
I let a flat near Marlow station. Can you help?
Yes. We work for letting agents and landlords as well as householders. You can call 0345 464 0079 or email us with the details for a clear quote.
Is there any odour?
Sometimes, a little. It fades as the sealant cures, and ventilation helps.
Do I have to be there?
If the work is inside, we need someone to let us in. Once we have agreed the job, you do not need to watch us work.
My new home is still under warranty. Should I contact you?
If you’re still within the builder’s snagging or warranty period, report it to them first. If it isn’t sorted, or keeps failing, get in touch with us.
Do you remove the old sealant?
Yes. All of the old material is cut out and the joint cleaned before resealing.
When is the sealant fully cured?
Most sealants are touch-dry well before they’re fully cured. We will give you the cure time for the product we used before we leave.
Will you leave a mess?
No. The area is protected while we work and cleaned up afterwards.
Landlord and commercial work in Danesfield
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.
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance that we can handle for you.
How the job changes by surface
Windows and doors
A draught at a new window can be a missed or failed joint. We look at the joints and reseal where needed.
Kitchens
As a new house dries, worktops and walls shift a little, opening gaps behind the upstand. We reseal them with a flexible sealant.
How it works
On the day, we look over the joints with you first, so there are no surprises. We protect the surfaces around the joints before any work starts. The work generally takes a few hours in a single home. In a small place like Danesfield, access is generally 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.
- The failed sealant is removed completely, with no layer left behind.
- 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.
Preparing for the visit
- Let us know about earlier repairs to the joints
- Where the joints are inside, avoid wetting them before we arrive
- Plan for the work area to be out of bounds to pets and children
Ask for a quote
The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints, and add pictures by email if you can.

DIY sealant or a professional job?
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
