Joints and finishes in Sandwich homes
Sandwich is close to the coast. New homes near the sea put their outside mastic to work from day one, so it’s worth checking at snagging. Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
In and around Sandwich, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

Your questions about new build mastic in Sandwich
Will you come out to Sandwich?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
I let a flat near Sandwich station. Can you help?
Yes, rental work is part of what we do. You can phone 0345 464 0079 or drop us an email with the address and a few details, and we will give you a fixed price before work begins.
Why does sealant fail so quickly in new builds?
Lots of new homes see sealant crack early, because the house is drying and settling. Poor preparation at handover adds to it.
Do the sealants smell?
There can be a smell while the sealant cures, but it fades. Opening a window helps.
When is the sealant fully cured?
It depends on the product. We tell you how long to leave it before we go.
Do you guarantee your work?
Yes: twelve months. If anything is not right with the work within the year, let us know and we will sort it.
Do you work for developers?
Yes. We take on second-fix sealant work across new plots. Good preparation keeps snagging to a minimum.
What should I tell you?
Where the job is, what the problem is and roughly how big it is. If you can, email a few pictures.
Different surfaces, different methods
Show homes
We can refresh show-home sealant that has discoloured or been knocked. We cut it out and reseal neatly.
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 with baths filled first.
Why deal with it now?
A hairline gap at a skirting can wait, but water getting through can’t. Not sure whether yours can wait? You can call 0345 464 0079 or drop us an email with a few pictures. Around Sandwich, water from a failed joint in an older home can soak into timber and plaster, and that is a much bigger job than renewing the sealant.

What we’re called out for in Sandwich
A new house holds a lot of water from the build, which takes a year or two to dry out. As it does, timber shrinks and joints open.
Any of these means the joints need attention:
- Sealant work across a run of new homes
- Sealant applied over dusty or wet surfaces
- Smeared, uneven beads picked up at snagging
- Kitchen sealant that has pulled off the wall
For new homes near Sandwich station, it’s worth checking the sealant early, while snags are still fresh.
What your quote should include
- Whether they seal over old material or remove it
- What product goes in the joint
- Which colour the sealant will be
- What the cure time is
DIY sealant or a professional job?
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.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
The process
At the end, we look at the finished work together and tell you how long to leave it. The visit itself normally takes anything from a few hours to several days, depending on the number of plots, depending on how much there is to do. A visit to Sandwich is planned like any other: the time, the access and where to park are agreed in advance. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- The failed sealant is removed completely down to clean surfaces.
- Joints are vacuumed and cleaned of building dust.
- We prime where needed and apply a sealant suited to each joint.
- We tool every joint neatly and tell you when each area can be used.
How to prepare
- Mention any parking rules near the property
- Tell us about access, such as stairs, a lift or high-level joints
- Let us know if you’ve seen damp or leaks
Ask for a quote
Asking for a quote is easy: tell us what needs doing and where and its rough size. A few photos by email make the job easier to understand.

How to look after the new joints
A little care helps the new joints last. We recommend:
- Wipe joints with warm soapy water
- Open a window or run the fan after bathing
- Check bath and shower seals every few months as the house settles
- Report sealant problems to your builder during the snagging period
Do not stand on the bath edge or the lip of the tray while the sealant cures. Report any movement in a bath or tray.
Report failed sealant to the builder while you are in the snagging period. After that, putting it right may fall to you so report it promptly.
When it isn’t the sealant
We’ll always be straight with you, so here’s what sealant cannot fix:
- Deciding who is responsible under a builder’s warranty
- Damaged fittings that need replacing
- Plumbing faults behind the sealant
Not sure which it is? You can ring 0345 464 0079 or email us and we will tell you honestly before booking.
