About our new build mastic in Liss
We work in new homes and on new-build sites across Liss. One shower or a whole phase of plots, the method doesn’t change: remove, clean, prime where needed, then a neat new bead. We work on windows & doors, show homes and bathrooms & en suites, and people most often call us about second-fix sealing on new plots and sealant applied over dusty or wet surfaces.
In smaller places like Liss, new homes tend to come as small developments or single plots. The sealant around baths, showers, frames and skirtings needs to be right from the start.
We guarantee the work for a year. If something isn’t right with it in that time, tell us and we’ll put it right.

What affects the quote in Liss
There’s no set price list, because jobs vary so much. The quote depends on:
- How easy the joints are to reach
- Which sealant suits the joint
- How many rooms, windows or areas are involved
- Mould in or behind the old joints
Leaving a failed joint normally makes the job bigger, not smaller, because water and mould keep working on it. If you’re unsure, ring 0345 464 0079 or send us an email for an honest opinion and a quote.
What to tell us for a quote
To help us quote quickly, please include:
- If it’s domestic, commercial or a hotel
- Access, such as stairs, a lift or height
- How many joints, rooms or windows are involved
- Photos by email, if that is easy
To get a quote, call 0345 464 0079 or send us an email with the location and a short description of the problem. You’ll have a clear quote before any work starts.
What happens if it’s left?
A hairline gap at a skirting can wait, but a leaking seal can’t. Not sure whether yours can wait? You can phone 0345 464 0079 or drop us an email with a few pictures and we will give you a straight answer. In an older home around Liss, damp from a failed joint can get into timber and plaster, which is far harder to put right than the sealant itself.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. Your quote takes all of that into account.

How the job changes by surface
Bathrooms and en suites
En suite showers are a common source of leaks into the room below. A proper reseal keeps water in the tray.
Windows and doors
External mastic around new windows and doors is sometimes rushed or missed. It’s resealed with an exterior sealant suited to the frame and wall.
Common questions in Liss
Will you come out to Liss?
Yes, we do. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Do you work for landlords with property near Liss station?
Yes, landlords and agents are among the people we work for. You can ring 0345 464 0079 or email us with the details for a clear quote.
Can new sealant go on top of the old bead?
No. Sealing over old sealant looks fine for a few weeks, then lifts. We remove every bit of the old bead before resealing.
Do you hold any approvals?
Yes. We hold ARBOMaster approved applicator status and we are fully insured too.
How long does the job take?
That depends on how much there is to do, but as a guide it takes a few hours for most snagging lists, longer for a run of plots. We’ll give you a better idea when we quote.
Do you use white or clear sealant?
It depends on the joint: white or clear in most bathrooms, and a colour to suit worktops, frames and floors elsewhere. We will agree it with you first.
Will you leave a mess?
We keep the work tidy. Nearby surfaces are protected, and the area is left clean when we finish.
Do you take on second-fix sealing for builders?
Yes. We take on second-fix sealant work across new plots. We clean and prime joints properly to keep callbacks down.
New homes and floors in Liss
London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.

When to call us in Liss
Once people move in, baths and trays take weight and bed down. A bath sealed empty drops slightly when filled, straining the joint.
It’s worth asking for a quote if you see:
- Gaps opening as the house dries out and settles
- Worktop and upstand sealant coming away
- New-build shower sealant that has already split
- Skirting joints opening in the first winter
If you’ve bought a new home near Liss station, the sealant around baths, showers and frames is worth checking in the first year or two.
What to look for in a quote
- Are they insured?
- How the surfaces are prepared before sealing
- What happens if they find a problem under the old sealant
- The length of the guarantee
Should I try it myself first?
If you are 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 fails, we can still redo it.
What a professional job adds is preparation and the right 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 the visit works
The work is kept neat and contained to the area we are working on, so you can carry on as normal. Expect the work to take a few hours in a single home. In a smaller place like Liss, 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.
- First we work through your snagging list or plot schedule with you.
- We cut out every bit of the failed or messy sealant.
- Each joint is cleaned of dust and grit, then primed if required.
- 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.
Getting ready for the visit
- Where the joints are inside, avoid wetting them before we arrive
- Let us know about parking restrictions
- Clear the area around the work
