New build mastic for homes and businesses in Orchard Leigh
Building dust is behind a lot of failed new-build sealant. We clean every joint thoroughly and prime where the surface and product need it, so the sealant actually sticks instead of bonding to the dust. We work on kitchens, plot handovers and show homes, and people most often call us about plot mastic for developers ahead of handover and smeared, uneven beads picked up at snagging.
Older homes in small places like Orchard Leigh often have timber floors that move with the seasons, so skirting and threshold joints need a flexible sealant rather than a rigid filler.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

Why deal with it now?
A quick bead over the top of the old sealant can look fine at first, but it won’t bond to the old layer. A lasting seal starts with removing the old one completely. Where a wall is exposed, as many are in small places like Orchard Leigh, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.

FAQs for Orchard Leigh
I let a flat near Berkhamsted station. Can you help?
Yes, rental work is part of what we do. You can ring 0345 464 0079 or email us with the address and a few details, and we’ll give you a fixed price before work begins.
Do you cover Orchard Leigh for new build mastic?

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.
Can new sealant go on top of the old bead?
No. We always remove the existing bead, the joint cleaned and primed where needed, and a new bead applied.
What does new build mastic cost?
We do not publish prices, because the cost depends on the job: how much there is, what’s there now, how we reach it and what it needs. We agree the price before any work begins.

Tell us what needs doing and where, plus photos if you have them. If we need more, we’ll ask.
Do I need to be at home?
If the work is inside, we need someone to let us in. After that, you can carry on with your day.
Looking after it afterwards
A little care helps the new joints last. We recommend:
- Follow the cure time we give you
- Act quickly if a seal starts to leak
- Ventilate bathrooms well, especially in the first year
- Record problems with dated photos
Don’t stand on the bath edge or the lip of the tray. Report any movement in a bath or tray.
Mould takes hold quickly in sealant that has gaps or lifted edges. Dealing with it before it goes black keeps the job straightforward.

What affects the cost of new build mastic
Call for a quick quote. What matters most is:
- Mould in or behind the old joints
- Working hours on commercial sites
- How much there is to do
- How many areas need sealing
A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. We take all of that into account in your 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:
- Access, such as stairs, a lift or height
- What’s wrong with the joints now
- Photos by email, if that is easy
- Where the job is, and your postcode
Quotes start with a quick conversation. Tell us what’s wrong, where it is and how much there is, and we’ll talk you through what we’d do. Whenever you’re ready, phone 0345 464 0079 or send us an email.
DIY versus a professional finish
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so just mention it when you contact us.
The process
On the day, there’s very little for you to do. Show us the job and we will take it from there. The job generally takes a few hours for most snagging lists, longer for a run of plots. Somewhere like Orchard Leigh needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- We go through the snagging list or plot schedule and agree the joints to do.
- The old bead comes out in full, with no layer left behind.
- Surfaces are cleaned of building dust and primed where needed.
- A sealant chosen for each area goes in and is tooled smooth.
- We check every joint and tell you how long each needs to cure.
Before we arrive
- Tell us if parking is tricky
- Mention if the joints have been sealed before
- Tell us about any water getting in
