Common questions in Ascott Earl
Is Ascott Earl within the area you cover?
Yes, Ascott Earl is covered. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Do you cover Ascott Earl for new build mastic?
Yes. We work across London and the South East, and Ascott Earl is part of that. You can phone 0345 464 0079 or drop us an email and let us know what needs doing.
Can new sealant go on top of the old bead?
No. New silicone will not bond to old silicone, so sealing over the top fails quickly. The old sealant always comes out first.
How long will you be here?
Most jobs take a few hours in a single home. We’ll confirm how long when we quote.
What do you put in the joint?
Quality sealants from brands including Arbo and Everbuild, chosen to suit the joint. We explain the product when we quote.
How much does new build mastic cost in Ascott Earl?
Size, access and the old material all affect the cost. Ask us for a quote and we will talk you through it.
Can you work from my snagging list?
Yes. We often work straight from a snagging list. We’ll go through the sealant items and agree what we’ll do.
Can you do several jobs on one visit?
Yes, and it often makes sense. Combining jobs makes good use of the visit.
New build mastic for homes and businesses in Ascott Earl
We never seal over a failed new-build bead. Fresh silicone cannot bond to the old layer, so it all comes out before we clean, dry and reseal. Typical jobs include skirting joints opening in the first winter and beads laid onto grit and dust from the build, on windows & doors, kitchens and plot handovers.
In a village or hamlet like Ascott Earl, 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.
Our work is backed for twelve months.

New build mastic around Ascott Earl

Looking after it afterwards
Aftercare is simple:
- Keep photos and emails about snagging items
- Do not seal over failed sealant yourself
- Open a window or run the fan after bathing
- Act quickly if a seal starts to leak
Follow the cure time we give you before the area gets wet. Silicone is generally left for about a day to cure enough for use.
A failed seal in a new home lets water into joists, plasterboard and ceilings. Catching it early keeps the fix to the sealant.
Why deal with it now?
It often makes sense to do all the sealant items on a snagging list together. You get one visit and one clear quote for the lot. Where a wall is exposed, as many are in small places like Ascott Earl, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Combining jobs into one visit normally makes better use of the time than several visits, so tell us about everything that needs sealing. You’ll get one clear quote for the whole job.

Should I try it myself first?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
If you’re 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 the job involves on each surface
Plot handovers
Taking time over preparation reduces return visits. Dust from the build is removed first and primer used where needed.
Skirting and floors
Where the floor meets a bath panel or kitchen plinth, the joint keeps mop water out. They get a flexible, water-resistant sealant.
What affects the quote in Ascott Earl
There’s no set price list, because no two jobs are the same. The quote depends on:
- Whether the work is at height
- Mould in or behind the old joints
- The size of the job
- How many areas need sealing
No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all make a difference, and we’ll explain the quote if you ask.
Helping us quote
To make quoting easier, let us know:
- If it’s domestic, commercial or a hotel
- Pictures of the joints, sent by email
- The rough size of the job
- What the problem is, such as mould, gaps, leaks or cracking
Asking for a quote is easy: let us know what needs doing and where and its rough size. Photos by email help us understand the job, and we’ll come back to you with a quote.
What we do, step by step
Every visit runs the same way: we check the joints, mask and protect the surrounding surfaces, carry out the job and clear up. Most jobs take a few hours for most snagging lists, longer for a run of plots. Somewhere like Ascott Earl needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- We go through the snagging list or plot schedule and agree the joints to do.
- Failed or untidy sealant is cut out completely.
- Surfaces are cleaned of building dust and primed where needed.
- New sealant suited to each joint is applied and tooled neatly.
- We check every joint and tell you how long each needs to cure.
Preparing for the visit
- Tell us about access, such as stairs, a lift or high-level joints
- Mention any leaks or damp you’ve noticed
- For indoor joints, keep the area dry beforehand if you can
