How we handle new build mastic in Little Chalfont
A new build should have a neat, sound bead at every joint. When the finish is smeared, patchy or already cracking, it’s worth putting right early, before water gets into the floor or walls. If you are dealing with kitchen sealant that has pulled off the wall and gaps between new skirting and floors, we can help.
In and around Little Chalfont, floors range from older timber boards to tiles and newer finishes, from timber that moves with the seasons to tiles laid on concrete. Skirting and threshold joints need a sealant that suits the floor.
Every job is covered by our one-year guarantee, wherever you are in Buckinghamshire.

How the job changes by surface
Plot handovers
Plot mastic is carried out to the developer’s schedule. Joints are prepared properly before sealing.
Bathrooms and en suites
Baths, showers, basins and trays in new bathrooms are the most common new-build reseal. We cut out the failed bead, clean and prime, and reseal with anti-fungal sanitary silicone.
What we are called out for in Little Chalfont
Fresh sealant can be knocked or cut by trades finishing off. A bead disturbed before it has cured may never seal properly and it shows once the home is in use.
These are the problems we are asked about most:
- Leaking shower tray seals in a new home
- Skirting joints opening in the first winter
- Worktop and upstand sealant coming away
- Cracked sealant around new window and door frames
In and around Little Chalfont, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

How we quote for new build mastic
There’s no set price list, because no two jobs are the same. The quote depends on:
- The number of rooms or windows
- Whether there’s mould to deal with
- How much old sealant there is and how hard it is to remove
- The product the joint needs
Combining jobs into one visit is generally more efficient than separate visits, so it’s worth mentioning everything you’d like done. You’ll get one clear quote for the whole job.
What to tell us for a quote
To make quoting easier, let us know:
- How we’d reach the joints
- A few photos by email, if you can
- The type of property
- Whether it has been sealed before
If you’re in Little Chalfont and need new build mastic, call 0345 464 0079 or drop us an email. A short description of the job and where it is helps us quote, and we’ll agree the price before any work begins.
Looking after it afterwards
Once the sealant has cured, a few habits help it last:
- Don’t wait for the house to settle if water is getting through
- Raise failed sealant with the developer while you’re covered
- Don’t seal over failed sealant yourself
- Follow the cure time we give you
Avoid standing on the rim of the bath or the edge of the tray in the first few weeks. If a bath or tray moves when you stand in it, get it looked at.
Lifting sealant traps moisture and mould behind it. Dealing with it before it goes black keeps the job straightforward.
The process
Every visit runs the same way: we check the joints, protect the area around them, carry out the job and tidy away. It normally takes a few hours for most snagging lists, longer for a run of plots. In a smaller place like Little Chalfont, parking is seldom the issue; lanes, gates and long drives are worth mentioning. For outside work, side access and the height of the joints help us plan.
- Each joint is checked for movement before we start.
- Old sealant is cut out and the joints cleaned.
- 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
- Clear items away from the joints we’re working on
- Tell us if parking is tricky
- Where the joints are inside, avoid wetting them before we arrive

Can I do it myself?
What a professional job adds is preparation and the right 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.
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
Honest limits
We will not take on work that won’t last, so here’s what sealant can’t put right:
- Leaks from pipes, valves or wastes, which need a plumber
- Your warranty claim itself, which is between you and the builder
- Damaged fittings that need replacing
Not sure which it is? You can ring 0345 464 0079 or drop us an email and we will tell you honestly before booking.

Common questions in Little Chalfont
Will you come out to Little Chalfont?
Yes, Little Chalfont is covered. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Is Little Chalfont in your area for new build mastic?
Yes, Little Chalfont is within the area we cover. We work across London and the South East. Just call 0345 464 0079 or drop us an email with a few details of the job, and we will send you a clear quote.
Should I go to my builder first?
Report it to the builder first while you’re covered. Once that’s done, or if they will not put it right, we’ll cut it out and reseal it.
When is the best time to reseal in a new build?
It depends on whether water is getting through. A leaking shower or bath seal should be redone straight away, while small cosmetic gaps can wait a while.
Do you remove the old sealant?
Yes. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.
Will there be a smell?
It depends on the product. Some products have a noticeable smell, others very little.
Can you quote for more than one area?
Of course. Combining jobs makes good use of the visit, so mention them when you ask for a quote.
Is it normal for sealant to crack in a new home?
A new house dries and settles for a year or two, and sealant is often rushed onto dusty, unprimed surfaces. Either can make it fail early.
