Fingest New Build Mastic
We cover Fingest for plot mastic for developers and snagging failed sealant in new homes. Old sealant removed completely, joints prepared properly and a one-year guarantee.
- Untidy sealant flagged on a snagging list
- Joints pulling apart as timber shrinks
- New-build shower sealant that has already split
How we handle new build mastic in Fingest
If your new home has a leaking shower seal, open skirting joints or untidy sealant, we can help. While the builder’s snagging or warranty period runs, report it to them first and if that stalls, we can do it. We work on kitchens, bathrooms & en suites and skirting & floors, and common reasons people get in touch are sealant work across a run of new homes and joints pulling apart as timber shrinks.
Around Fingest, older homes often have timber floors that move through the year, which is why skirting and threshold joints need a flexible sealant, not filler.
You’re covered for a year from the day we finish. If anything isn’t right with it, phone 0345 464 0079 or send us an email.

DIY sealant or a professional job?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
When something else is needed
Sealant is not the answer to every problem, and we’d rather say so up front. Sealant won’t put right:
- Leaks from pipes, valves or wastes, which need a plumber
- Damaged fittings that need replacing
- Cracking that points to a structural problem
If in doubt, ring 0345 464 0079 or drop us an email and we will say what we think.
What we seal
- Bathrooms & en suites
- Plot handovers
- Windows & doors
- Kitchens
- Show homes
- Skirting & floors
For landlords and businesses
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance.
In hotels, rooms out of use cost money, so we plan the work room by room. We’ve worked in hotels as well as homes and businesses.
When to call us in Fingest
When the heating goes on in the first winter, the house dries fast. Gaps open along skirting, frames and worktops and cracks appear in the sealant.
The problems people normally mention when they call are:
- Cracks appearing as a new home settles
- Sealant that never bonded to the surface
- Second-fix sealing on new plots
- Smeared, uneven beads picked up at snagging
For new homes near Saunderton station, it’s worth checking the sealant early, while snags are still fresh.
What to look for in a quote
- Whether they’re fully insured
- Whether VAT is included
- How the surfaces are prepared before sealing
- Is the old sealant removed completely?
Looking after it afterwards
Aftercare is simple:
- Check bath and shower seals every few months as the house settles
- Open a window or run the fan after bathing
- Do not seal over failed sealant yourself
- Keep water off fresh sealant until it has cured
Wipe the sealant with warm soapy water. Avoid abrasive pads and strong solvents as they wear the bead.
A seal that splits early is often a sign of movement. Getting it resealed properly, and any movement checked, stops it recurring.

What affects the cost of new build mastic
The quote reflects the job in front of us. We look at:
- Working hours on commercial sites
- How many areas need sealing
- Mould in or behind the old joints
- The size of the job
The cost reflects the work involved, not guesswork. That’s why we ask about the job first and agree the price before starting.
What to tell us for a quote
Photos help, but a description is a good start. Please mention:
- The problem you’ve noticed
- Pictures of the joints, sent by email
- Whether it has been sealed before
- The type of property
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints, and email pictures if that’s easy.
FAQs for Fingest
Will you come out to Fingest?
Yes. Fingest is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
I let a flat near Saunderton station. Can you help?
Yes, rental work is part of what we do. Just call 0345 464 0079 or send us an email and tell us about the property, and we’ll send you a clear quote.
Should I try DIY first?
You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. If it doesn’t work out, we can redo it.
How do I get a quote for new build mastic in Fingest?
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. You will get a clear quote before work begins.
Will the old sealant be removed?
Yes, always, and completely. New silicone doesn’t stick to old silicone, so any old material comes out before anything new goes in.
How long does the job take?
Typically it takes anything from a few hours to several days, depending on the number of plots. Larger jobs naturally take longer, and we will say how long yours will take.
Can you do several jobs on one visit?
Yes, and it often makes sense. Doing several areas at once is generally more efficient, so mention them when you ask for a quote.
Do the sealants smell?
Some sealants have a smell while they cure, which fades as it sets. Ventilation helps.
How the visit works
All our tools and materials come with us in the van. After a quick look at the joints together, we protect the area and start. Most jobs take a few hours in a single home. In a small place like Fingest, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.

- We remove the failed sealant and clean the joints.

Getting ready for the visit

- Mention any sign-in or site rules at work premises
- Let us know if you’ve seen damp or leaks
