FAQs for Swinbrook
Do you cover smaller places like Swinbrook?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Do you cover Swinbrook for new build mastic?
Yes, Swinbrook is within the area we cover. Our work covers London and the South East. You can ring 0345 464 0079 or email us and tell us what needs doing, and we’ll give you a clear price.
Do you work through snagging lists?
Yes. Send the list and a few pictures of the sealant items, and we will quote. We will tell you if anything on it isn’t a sealant job.
Why does sealant fail so quickly in new builds?
Lots of new homes see sealant crack early. Rushed application on dusty surfaces makes it worse.
Will it make a mess?
No. We protect the surfaces around the joints, and we tidy up before we go.
Where are you based?
Our base is Crawley, with over 20 years’ experience. We work across South East England, London and Scotland.
Do the sealants smell?
It depends on the product. Some smell for a while, some hardly at all, and any smell fades as they cure.
What do you need from me for a quote?
The location, the problem and the rough size of the job. Photos by email help too.
What affects the quote in Swinbrook
You will get a clear quote before we start. It’s based on:
- Working hours on commercial sites
- How much there is to do
- How much old sealant there is and how hard it is to remove
- Which sealant suits the joint
Doing several joints on one visit usually makes better use of the time than several visits. You’ll get one clear quote for the whole job.
What we need to know
The more you tell us, the more accurate the quote. When you ask for a quote, tell us:
- Where the job is, and your postcode
- Access, such as stairs, a lift or height
- Pictures of the joints, sent by email
- Any previous sealing or DIY work
Getting a quote is simple: tell us what needs doing and where. Photos by email help us understand the job.
Leave it or put it right?
If you are still in the builder’s snagging or warranty period, ask them to put it right first. If it keeps failing or isn’t dealt with, we can reseal it properly. Older cottages and farmhouses around Swinbrook can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
There are no prices on our website, because the cost depends so much on the job itself. Call for a quick quote and we will talk you through it.

How it works
At the end, we look at the finished work together. The visit itself usually takes anything from a few hours to several days, depending on the number of plots, depending on how much there is to do.

Everything for the job comes with us, so a second trip is avoided where possible.

- Old sealant is cut out and the joints cleaned.

What we are called out for in Swinbrook
Baths and trays settle under load once the home is lived in. A bath sealed empty drops slightly when filled, straining the joint and the sealant may split.
Most people get in touch when they notice something like this:
- Cracked sealant around new window and door frames
- Beads laid onto grit and dust from the build
- Skirting joints opening in the first winter
- Gaps behind new kitchen upstands
If you’ve bought a new home near Shipton station, the sealant around baths, showers and frames is worth checking in the first year or two.

Surface by surface
Skirting and floors
Where the floor meets a bath panel or kitchen plinth, the joint keeps mop water out. They get a flexible, water-resistant sealant.

We seal show-home bathrooms, kitchens and frames ready for viewings. We’ll plan around viewing times.
When it is not the sealant
Before you book, it’s worth knowing the limits:
- Leaking fittings rather than failed sealant

- Deciding who is responsible under a builder’s warranty
