DIY versus a professional finish
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
A DIY attempt does not rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.
What the job involves on each 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.
Windows and doors
Internal joints between frames and plaster often crack as a new house dries. We cut out the cracked bead and reseal with a flexible sealant.
Joints and finishes in Snowdown homes
Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
For new homes near Snowdown station, it’s worth checking the sealant early, while snags are still fresh.

When to call us in Snowdown
A new house holds a lot of water from the build, and it dries out over the first couple of years. As it does, timber shrinks and joints open.
People usually contact us after spotting something like this:
- Gaps behind new kitchen upstands
- Cracked caulk along new skirting
- Leaking shower tray seals in a new home
- Sealant work across a run of new homes
Around Snowdown, as everywhere, new build mastic is only as good as the preparation behind it.

Why it’s worth doing now in Snowdown
If you’re still in the builder’s snagging or warranty period, ask them to put it right first. If it’s slow, or the same joint keeps failing, a proper reseal from a specialist is the next step. Older cottages and farmhouses around Snowdown can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Combining jobs into one visit is generally more efficient than separate visits, so it’s worth mentioning everything you’d like done. We’ll give you a clear quote for the lot.

Questions from Snowdown
Is Snowdown within the area you cover?
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.
Can you help a landlord with a rental near Snowdown station?
Yes, rental work is part of what we do. You can phone 0345 464 0079 or send us an email with the address and a few details, and we’ll give you a fixed price before any work starts.
How long before the joint can be used?
Many sealants skin over quickly but take longer to cure fully. We will give you the cure time for the product we used before we leave.
What do you put in the joint?
We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice, and we’ll tell you what we’re using.
Do I need to be at home?
For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.
Do you do commercial work?
Yes. We can plan bigger jobs in stages to suit the site.
Is there any odour?
Some sealants have a smell while they cure. Opening a window helps.
Are you fully insured?
Yes. We’re fully insured for every job we do.
The process
On the day, there’s very little for you to do. Point us to the joints and we’ll get on with it. The job generally takes a few hours in a single home from start to finish.

- We look at why each joint failed, including any movement.
- We remove the failed sealant and clean the joints.
- Joints are dried and primed where the product calls for it.
- Baths are filled with water, then the new sealant is applied.

Quotes for new build mastic in Snowdown
We quote each job individually. These are the things that affect it:
- Any working-time requirements on site
- Whether the work is at height
- The old material and how stubborn it is
- Which sealant suits the joint
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. We take all of that into account in your quote.
Asking for a quote
You don’t need to know the technical terms. Just tell us:
- The problem you’ve noticed
- Any previous sealing or DIY work
- Pictures of the joints, sent by email
- The type of property
It all starts with a short chat. Tell us what’s wrong, where it is and how much there is, and we will explain how we’d tackle it. When it suits you, call 0345 464 0079 or send us an email.
Looking after it afterwards
Joint life depends on how it’s used and looked after. We suggest:
- Report sealant problems to your builder during the snagging period
- Wipe joints with warm soapy water
- Avoid running a DIY bead over the old one
- Keep water off fresh sealant until it has cured
Watch the joints as the house settles. Small gaps can appear as the house dries.
A seal that splits early is often a sign of movement. Getting it resealed properly, and any movement checked, stops it recurring.
