New build mastic for homes and businesses in Ashley Green
Across Ashley Green, we work for both new-home owners and the builders handing those homes over. One shower or a whole phase of plots, the method does not change: remove, clean, prime where needed, then a neat new bead. We work on windows & doors, skirting & floors and show homes, and common reasons people get in touch are sealant applied over dusty or wet surfaces and kitchen sealant that has pulled off the wall.
In a village or hamlet like Ashley Green, new homes are more likely to be a barn conversion or a handful of houses than a big estate. Each still needs its sealant and floor joints finished properly.
The work is covered for a year after we finish. If anything isn’t right with it, call 0345 464 0079 or send us an email.

Quotes for new build mastic in Ashley Green
Your quote is based on your job. We take into account:
- Any working-time requirements on site
- How many areas need sealing
- Which sealant suits the joint
- Whether the work is at height
Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part, and we will explain the quote if you ask.
Asking for a quote
When you contact us, these details help:
- Photos by email, if that’s easy
- What the problem is, such as mould, gaps, leaks or cracking
- Access, such as stairs, a lift or height
- Any previous sealing or DIY work
There’s no standard price list, as no two jobs are quite the same. Instead, we give you a clear quote for your job. To get started, ring 0345 464 0079 or email us.
What happens on the day
Once we are on site, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. Most jobs then take anything from a few hours to several days, depending on the number of plots. In a small place like Ashley Green, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We look at why each joint failed, including any movement.
- We remove the failed sealant and clean the joints.
- Joints are dried and primed where the product calls for it.
- New sealant goes in, with baths filled first so they’re at their heaviest.
- We check every joint and leave you with the cure times.
Before we arrive
- Mention if the joints have been sealed before
- Tell us about access, such as stairs, a lift or high-level joints
- Let us know about parking restrictions

Leave it or put it right?
A tube of sealant from the DIY shop will not fix the cause: dust, no primer and old sealant left in the joint. Proper removal and preparation are what make it last. Where a wall is exposed, as many are in small places like Ashley Green, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.

Ashley Green: your questions answered
Will you come out to Ashley Green?
Yes, smaller places are covered as well as towns. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Can you help a landlord with a rental near Berkhamsted station?
Yes, rental work is part of what we do. Just phone 0345 464 0079 or send us an email and tell us about the property, and we’ll give you a clear price.
Can I send you my snagging list?
Yes. We often work straight from a snagging list. We agree the sealant items with you before we start.
What information do you need?
A short description and the location, plus photos if you have them. We will ask anything else we need to know.
Do you take out the old sealant first?
Yes. All of the old material is cut out and the joint cleaned before resealing.
Do you guarantee your work?
Yes, for a year. If there’s a problem with our work in that time, tell us and we will put it right.
Which products do you use?
Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference, and we will tell you what we are using.
Can I do it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.
When it isn’t the sealant
We won’t take on work that will not last, so these are the limits:
- Settlement cracks that need a surveyor
- Leaking fittings rather than failed sealant
- A tray or bath that is not properly supported, until it’s fixed
If you’re not sure, just call 0345 464 0079 or email us and we will give you a straight answer.

Aftercare tips
Looking after new joints is easy:
- Report sealant problems to your builder during the snagging period
- Photograph failed sealant before it’s redone
- Avoid running a DIY bead over the old one
- Ventilate bathrooms well, especially in the first year
Photograph failed sealant before it’s redone and keep the builder’s replies. It’s useful if you need to raise other issues later.
Early snagging is easier snagging. Left alone, a small crack can become a leak.
