How we handle new build mastic in Golden Cross
In a new home, every joint should have a clean, even bead. When the finish is smeared, patchy or already cracking, it’s worth putting right early, before water reaches anything behind it. We’re often asked to deal with sealant applied over dusty or wet surfaces and new-build shower sealant that has already split, on show homes, plot handovers and bathrooms & en suites.
In a village or hamlet like Golden Cross, new homes are more likely to be a barn conversion or a handful of houses than a big estate. Every one needs its sealant and floor joints done properly, whatever the size of the site.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

How we quote for new build mastic
The price is agreed before any work begins. It takes into account:
- How many rooms, windows or areas are involved
- Working hours on commercial sites
- The old material and how stubborn it is
- The amount of work

- Photos by email, if that is easy
- Any access issues, like height or stairs

The process
At the end, we look at the finished work together. The visit itself normally takes a few hours in a single home, depending on the size of the job. Somewhere as small as Golden Cross, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We start by going through the snagging items or plot schedule with you.
- Every bit of the old builder’s sealant is cut out.
- Joints are vacuumed and cleaned of building dust.
- 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.
Getting ready for the visit
- Let us know about parking restrictions
- Let us know about earlier repairs to the joints
- Clear the area around the work
Getting a quote
A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is, and email photos if that’s easy.
Advice
What the job involves on each surface
Windows and doors
The gap between a new frame and its plaster reveal often opens up. We cut out the cracked bead and reseal with a flexible sealant.
Kitchens
Worktops in new homes can move slightly as the house dries, opening gaps behind the upstand. A fresh flexible bead closes them.
Common problems we fix in Golden Cross
If plaster or screed was still damp when it was sealed, the bond suffers. Site programmes do not always leave time for joints to dry before the sealant goes on.
Any of these means the joints need attention:
- Shower seals failing in the first year or two
- Joints pulling apart as timber shrinks
- Internal frame sealant that has split
- Messy sealant that spoils new finishes
In and around Golden Cross, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

Is it messy?
Tidy work is part of the job. We protect what’s around the joints, and the area is left clean when we finish.
Can I add another job to the visit?
Yes. Tell us about everything you’d like done and we will quote it together.
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.
What should I tell you?
Where the job is, what the problem is and roughly how big it is. Photos by email help too.
When is the sealant fully cured?
Cure times vary by product and the temperature. Before we leave, we’ll tell you the cure time.
Do you work for developers?
Yes. Second-fix sealing in bathrooms, kitchens, frames and floors is part of what we do. We clean and prime joints properly to keep callbacks down.
Should I try it myself first?
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
Why it’s worth doing now in Golden Cross
A quick bead over the top of the old sealant can look fine at first, but it won’t bond to the old layer. Taking it all out and starting again is the only way to get a lasting seal. Where a wall is exposed, as many are in small places like Golden Cross, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
What it costs depends on the amount of work, how hard the old material is to remove and access to the work. We give a clear quote before we start, so you know where you stand.
