New build mastic in Lake End, done properly
Failed shower seals, gaps along the skirting and messy beads are common items on a new-home snagging list. While the builder’s snagging or warranty period runs, report it to them first, and if it is not put right, get in touch with us. We work on kitchens, show homes and skirting & floors, and common reasons people get in touch are beads laid onto grit and dust from the build and cracked sealant around new window and door frames.
Work in a small place like Lake End just needs the journey and access planning, and the work itself is the same as on any site.
A one-year guarantee comes as standard.

How we quote for new build mastic
Your quote is based on your job. We look at:
- Any mould that needs treating
- Working hours on commercial sites
- Whether old sealant or filler has to be cut out
- The number and length of the joints
The cost depends on the size of the job, how hard the old material is to remove and access to the work. We give a clear quote before any work starts, so you know where you stand.
What to tell us for a quote
The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:
- Whether it has been sealed before
- Any access issues, like height or stairs
- If it’s domestic, commercial or a hotel
- Photos by email, if that’s easy
Every job is quoted individually. Simply phone 0345 464 0079 or email us and describe the job, and photos are welcome.
Why act early in Lake End
A tube of sealant from the DIY shop will not fix the cause: dust, no primer and old sealant left in the joint. Cutting out, cleaning and priming are what make the difference. Around Lake End, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
What you pay reflects the work, not a rough estimate. That’s why we ask a few questions first.

How it works
On the day, we look over the joints with you first, so there are no surprises. Surfaces next to the work are protected before any work begins. Most jobs take a few hours for most snagging lists, longer for a run of plots. Somewhere like Lake End 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.
- First we work through your snagging list or plot schedule with you.
- We cut out every bit of the failed or messy sealant.
- Each joint is cleaned of dust and grit, then primed if required.
- 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
- Let us know about parking restrictions
- Mention if the joints have been sealed before
- Plan for the work area to be out of bounds to pets and children

Should I try it myself first?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
Joints and finishes in Lake End homes
Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
For new homes near Burnham station, it’s worth checking the sealant early, while snags are still fresh.

Lake End questions
Do you cover Lake End for new build mastic?
Yes. Our work covers London and the South East, and Lake End is part of that. Just phone 0345 464 0079 or email us with a few details of the job, and we will send you a clear quote.
Will you come out to Lake End?
Yes, we do. We work across London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
My new home is still under warranty. Should I contact you?
While the snagging or warranty period runs, the builder should be your first contact. If they’re slow or the fix doesn’t last, we can help.
What information do you need?
Only a few details: the address or postcode, what’s wrong and any access issues. Then phone 0345 464 0079 or send us an email.
Will you leave a mess?
We keep the work tidy. Nearby surfaces are protected.
Can you reseal over the builder’s sealant?
No. New silicone won’t bond to old silicone, so it soon lifts and traps water. We cut the old bead out completely.
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.
Are you an approved applicator?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.
When to call us in Lake End
Sealant applied onto damp surfaces doesn’t bond well. On a busy site, joints aren’t always given time to dry before the sealant goes on.
Any of these means the joints need attention:
- Sealant that never bonded to the surface
- Untidy sealant flagged on a snagging list
- Sealant work across a run of new homes
- Frame joints opening as the plaster dries
In and around Lake End, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.
What your quote should include
- What preparation is included
- Whether they seal over old material or remove it
- Which colour the sealant will be
- Is VAT in the price?
