New build mastic for homes and businesses in Fernhurst
Dust is the enemy of new-build sealant. We clean every joint thoroughly and prime where the surface and product need it, so the sealant actually sticks. We’re often asked to deal with cracked sealant around new window and door frames and beads laid onto grit and dust from the build, across kitchens, show homes and windows & doors.
In a village or hamlet like Fernhurst, 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.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we’ll sort it.

Different surfaces, different methods
Show homes
Show homes need sealant that looks right from day one. We lay neat, even beads in colours to suit the finishes.
Skirting and floors
New homes often develop a gap between skirting and floor. We seal it with a flexible sealant that copes with the movement.
Should I try it myself first?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly.
What affects the cost of new build mastic
Call for a quick quote. The main things that affect it are:
- Working hours on commercial sites
- How many rooms, windows or areas are involved
- How easy the joints are to reach
- The old material and how stubborn it is
No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference.
Helping us quote
To make quoting easier, please include:
- If someone has resealed it before
- How many joints, rooms or windows are involved
- Pictures of the joints, sent by email
- Any access issues, like height or stairs
If you’re in Fernhurst and need new build mastic, phone 0345 464 0079 or email us. Tell us what the problem is and where, and you will get a clear quote before work begins.
How it works
You do not need to clear the whole room or building before we come, only the area right around the joints. We protect the rest, and the job takes anything from a few hours to several days, depending on the number of plots for a typical job. Somewhere as small as Fernhurst, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We start by agreeing which joints are on the list, from the snagging sheet or plot schedule.
- Failed or untidy sealant is cut out completely.
- We clean off dust from the build and prime the surfaces where the product needs it.
- We apply a sealant that suits each joint and tool it to a neat finish.
- Each area is checked and left with its cure time.
Getting ready for the visit
- Mention any tricky access
- Clear the area around the work
- Let us know about parking restrictions

Looking after it afterwards
To keep the joints looking good and working properly:
- Do not seal over failed sealant yourself
- Check bath and shower seals every few months as the house settles
- Avoid scourers and strong chemicals on sealant
- Report sealant problems to your builder during the snagging period
Follow the cure time we give you before the area gets wet. Silicone is normally left for about a day before water reaches them.
If a shower tray or bath seal splits in the first year, look for movement. Have it resealed, and the tray or bath checked, before it gets worse.
Why it’s worth doing now in Fernhurst
Sealant done properly at handover means fewer callbacks. Every return visit for a failed seal takes time and most come down to preparation. In a small place like Fernhurst, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Leaving a failed joint usually makes the job bigger, not smaller, as water and mould keep getting in. If you are unsure, call 0345 464 0079 or email us and we will give you an honest view and a quote.

Common questions in Fernhurst
Can you do new build mastic in Fernhurst?
Yes. We work across London and the South East, and Fernhurst is part of that. You can ring 0345 464 0079 or drop us an email and let us know what needs doing.
Can you help a landlord with a rental near Haslemere station?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. You can ring 0345 464 0079 or drop us an email with the details for a clear quote.
When is the best time to reseal in a new build?
For failed seals that let water through, the best time is now. For small cosmetic gaps, waiting until the house has settled can save doing them twice.
Can I add another job to the visit?
Yes, and it often makes sense. Combining jobs makes good use of the visit.
How long does new build mastic take?
Typically it takes a few hours for most snagging lists, longer for a run of plots. Bigger jobs take longer.
Does someone need to be in?
If the work is inside, we need someone to let us in. After that, you can carry on with your day.
When is the sealant fully cured?
Most sealants are touch-dry well before they’re fully cured. We’ll give you the cure time for the product we used before we leave.
Why does sealant fail so quickly in new builds?
A new house dries and settles for a year or two, and sealant is often applied quickly onto dusty surfaces. Either can make it fail early.
