Joints and finishes in Mill Hill homes
Mill Hill is close to the coast. Plot mastic on new homes near the coast takes more weather than it would inland, so any gaps are best picked up early. The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
For new homes near Walmer station, it’s worth checking the sealant early, while snags are still fresh.

New build mastic in Mill Hill, done properly
Across Mill Hill, we work for both new-home owners and the builders handing those homes over. One shower or a whole phase of plots, the method does not change: remove, clean, prime where needed, then a neat new bead. We work on bathrooms & en suites, skirting & floors and windows & doors, and people most often call us about worktop and upstand sealant coming away and cracks appearing as a new home settles.
If you’ve bought a new home in or near Mill Hill, the first year or two is a good time to check the sealant. Gaps at skirtings, shower seals pulling away and missing mastic around frames are common snags.
Each job carries a 12-month guarantee.

What sealant work can’t fix
Honest advice matters more to us than a booking, so here’s what sealant cannot fix:
- Your warranty claim itself, which is between you and the builder
- Cracked trays, tiles or worktops
- Leaks from pipes, valves or wastes, which need a plumber
If you are not sure, just ring 0345 464 0079 or drop us an email and we will give you a straight answer before booking.
Surfaces we seal
- Show homes
- Windows & doors
- Bathrooms & en suites
- Skirting & floors
- Kitchens
- Plot handovers
Keeping the joints in good condition
After the cure time, these simple habits help:
- Report sealant problems to your builder during the snagging period
- Open a window or run the fan after bathing
- Get a leaking seal dealt with right away
- Clean sealant with mild detergent, not abrasives
Keep the bathroom ventilated, especially in the first year. Use the extractor fan or open a window after showers.
If a shower tray or bath seal splits in the first year, look for movement. Getting it resealed properly, and any movement checked, stops it recurring.
Common questions in Mill Hill
I let a flat near Walmer station. Can you help?
Yes, we work for letting agents and landlords. Just ring 0345 464 0079 or send us an email and tell us about the property, and we’ll give you a clear quote.
Do you cover smaller places like Mill Hill?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Should I go to my builder first?
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.
Do you hold any approvals?
Yes. Mr Mastic is an ARBOMaster approved applicator and we’re fully insured too.
Can you work from my snagging list?
Yes. We often work straight from a snagging list. We agree the sealant items with you before we start.
Will there be a smell?
Possibly a little. It fades as the sealant cures.
Do you guarantee your work?
Yes: twelve months. If there’s a problem with our work in that time, tell us and we’ll put it right.
Do you remove the old sealant?
Yes. All of the old material is cut out and the joint cleaned before applying anything new.
Different surfaces, different methods
Bathrooms and en suites
Shower trays in new homes often move slightly in the first year. We reseal once the old bead is fully out.
Kitchens
As a new house dries, worktops and walls shift a little, opening gaps behind the upstand. A fresh flexible bead closes them.
Work for landlords, hotels and businesses
Housing providers, facilities teams and property managers book us too. We can quote a run of properties together, and we are fully insured for the work.
Whether it’s one flat or a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.
What we do, step by step
Every visit runs the same way: we check the joints, protect the area around them, carry out the job and tidy away. Most jobs take anything from a few hours to several days, depending on the number of plots. A visit to Mill Hill is planned like any other: the time, the access and where to park are agreed in advance. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- We go through the snagging list or plot schedule and agree the joints to do.
- The old bead comes out in full, with no layer left behind.
- Surfaces are cleaned of building dust and primed where needed.
- We apply a sealant that suits each joint and tool it to a neat finish.
- Finally, each room is checked and you are given the cure time.
How to prepare
- Tell us about any previous sealing or DIY attempts
- Let us know about parking restrictions
- Plan for the work area to be out of bounds to pets and children

Advice
When to call us in Mill Hill
New homes are full of moisture from plaster, screed and concrete, and it dries out over the first couple of years. As it does, timber shrinks and joints open, and sealant that cannot keep up splits.
The most common problems we see are:
- Untidy sealant flagged on a snagging list
- Frame joints opening as the plaster dries
- Cracked caulk along new skirting
- Gaps opening as the house dries out and settles
In and around Mill Hill, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.
What to look for in a quote
- What insurance they hold
- What product goes in the joint
- How hidden problems are handled
- Who does the work, and how experienced they are
DIY versus a professional finish
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
If you do try it yourself, take your time over the 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.
