Can you do new build mastic in Northwood?

Will you leave a mess?
We keep the work tidy. We protect what’s around the joints.

Yes, we are fully insured for every job we do.
Can I send you my snagging list?
Yes. We often work straight from a snagging list. We agree the sealant items with you before work begins.
How long will you be here?
Typically it takes a few hours for most snagging lists, longer for a run of plots. Larger jobs naturally take longer, and we’ll tell you how long to expect.
What colour sealant will you use?
The colour is chosen to suit the tiles, worktop or frame. Tell us what you’d like when you get a quote.
Is it worth trying it myself?
Sometimes. Preparation is everything: all the old sealant out, and a clean, dry joint. We can always put it right if it fails.
New build mastic for homes and businesses in Northwood
Dust is the enemy of new-build sealant. We clean every joint thoroughly and prime where the surface and product need it, so the new bead bonds properly. Common call-outs are for kitchen sealant that has pulled off the wall and skirting joints opening in the first winter, across show homes, kitchens and windows & doors.
In smaller places like Northwood, new homes tend to come as small developments or single plots. Each still needs its sealant and floor joints finished properly from day one.
The work is guaranteed for twelve months. If something isn’t right with it in that time, tell us and we will put it right.

Landlord and commercial work in Northwood
In hotels, rooms out of use cost money, so the work can be planned room by room around your bookings where we can. We’ve worked in hotels as well as homes and businesses.
We also work for property managers and facilities teams. Several sites can go on one quote, and we are fully insured.
When to call us in Northwood
Later trades and the final clean can damage fresh sealant. A bead disturbed before it has cured may never seal properly, and the problem shows up after you move in.
People usually contact us after spotting one of these:
- Worktop and upstand sealant coming away
- Frame joints opening as the plaster dries
- Sealant that never bonded to the surface
- Messy sealant that spoils new finishes
In and around Northwood, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

How to look after the new joints
A little care helps the new joints last. Our advice:
- Wipe joints with warm soapy water
- Don’t wait for the house to settle if water is getting through
- Don’t seal over failed sealant yourself
- Raise failed sealant with the developer while you are covered
Ventilation matters in a new home, which is still drying out. Use the extractor fan or open a window after showers to help keep mould away.
Mould takes hold quickly in sealant that has gaps or lifted edges. Dealing with it before it goes black saves a harder job later.
New build mastic in Northwood: local notes
Northwood is within about 2 miles of the coast. New homes near the sea put their outside mastic to work from day one, 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.
If you’ve bought a new home near Ramsgate station, the sealant around baths, showers and frames is worth checking in the first year or two.

DIY sealant or a professional job?
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.

How it works
We keep the work tidy and contained to the joints we’re treating, so you can get on with your day. The job usually takes anything from a few hours to several days, depending on the number of plots, and we explain the cure time before we leave. In a smaller place like Northwood, 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.
- We start by agreeing which joints are on the list, from the snagging sheet or plot schedule.
- Failed or untidy sealant is cut out completely.
- We clean off dust from the build and prime the surfaces where the product needs it.
- 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.
Before we arrive
- Mention any sign-in or site rules at work premises
- Mention any leaks or damp you’ve noticed
- Mention any tricky access
