About our new build mastic in Upchurch
Across Upchurch, we work for both new-home owners and the builders handing those homes over. Whether it’s one en suite or a run of plots, the method is the same: cut out, clean, prime where needed and reseal neatly. We are often asked to deal with gaps opening as the house dries out and settles and cracked sealant around new window and door frames, across windows & doors, show homes and plot handovers.
Somewhere as small as Upchurch, new homes tend to be conversions, self-builds or a few houses rather than an estate. Every one needs its sealant and floor joints done properly, whatever the size of the site.
There’s a 12-month guarantee on every job, large or small.

What the job involves on each surface
Kitchens
Worktops in new homes can move slightly as the house dries, which opens gaps along the back. We reseal them with a flexible sealant.
Windows and doors
A draught at a new window can be a missed or failed joint. We look at the joints and reseal where needed.

Joints and finishes in Upchurch homes
Upchurch is within about 1 mile 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, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
For new homes near Rainham (Kent) station, it’s worth checking the sealant early, while snags are still fresh. Around Upchurch, as everywhere, new build mastic is only as good as the preparation behind it.

How the visit works
There’s no need to move everything out, only the area right around the joints. We protect the rest, and the job takes a few hours for most snagging lists, longer for a run of plots for a typical job. In a small place like Upchurch, access is usually the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We go through the snagging list or plot schedule and agree the joints to do.
- We cut out every bit of the failed or messy sealant.
- We clean off dust from the build and prime the surfaces where the product needs it.
- A sealant chosen for each area goes in and is tooled smooth.
- We check every joint and tell you how long each needs to cure.
Preparing for the visit
- Mention any parking rules near the property
- Clear items away from the joints we are working on
- Mention any leaks or damp you’ve noticed

What affects the cost of new build mastic
Some jobs are bigger than they look, and some smaller. The main factors:
- The old material and how stubborn it is
- Whether the work is at height
- The number of rooms or windows
- Which sealant suits the joint
Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all make a difference, and we will explain the quote if you ask.
Helping us quote
Before you ask for a quote, have a think about:
- How many joints, rooms or windows are involved
- If someone has resealed it before
- The type of property
- Where the job is, and your postcode
The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints, and add photos by email if you can.
Why deal with it now?
Water getting past a failed seal in a new build reaches walls and floors that are still settling. Dealing with it early keeps the damage away from ceilings, floors and finishes. In a small place like Upchurch, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Homes and businesses are quoted the same way: the amount of work, the access and the products needed. Ask us for a quote and we will go through it with you.

When something else is needed
In fairness, some problems need a different trade:
- Disputes or warranty claims with your builder
- Leaks from pipes, valves or wastes, which need a plumber
- Movement caused by a poorly fitted tray or bath
If you are not sure, just phone 0345 464 0079 or drop us an email and we will give you a straight answer.

Can I do it myself?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
