What the job involves on each surface
Plot handovers
We work through plots to your schedule, sealing each room ready for handover. Joints are prepared properly before sealing.
Skirting and floors
As timber and screed dry, skirting and floors shift. We use a flexible product rather than caulk painted or coloured to suit.
How we handle new build mastic in Hartley
If your new home has a leaking shower seal, open skirting joints or untidy sealant, we can help. If you’re still within the builder’s snagging or warranty period, tell them first. We work on skirting & floors, windows & doors and plot handovers, and common reasons people get in touch are leaking shower tray seals in a new home and frame joints opening as the plaster dries.
Somewhere as small as Hartley, new homes tend to be conversions, self-builds or a few houses rather than an estate. Each still needs its sealant and floor joints finished properly.
You are covered for a year from the day we finish. If anything isn’t right with it, call 0345 464 0079 or drop us an email.

What affects the quote in Hartley
Some jobs are bigger than they look, and some smaller. What affects the quote:
- The number and length of the joints
- How much old sealant there is and how hard it is to remove
- Any working-time requirements on site
- Access and height
We don’t show prices on the website, because the cost depends so much on the job itself. Call for a quick quote and we’ll talk you through it.
Asking for a quote
What to tell us when you ask for a quote:
- Whether it has been sealed before
- How many joints, rooms or windows are involved
- The problem you’ve noticed
- Any access issues, like height or stairs
Call for a quick quote, or send an email if you’d rather. Tell us about the joints that need doing and we’ll talk you through the work before giving you a price.
DIY versus a professional finish
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly.
New homes and floors in Hartley
Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
In and around Hartley, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint. For jobs in and around Hartley, choosing the right material for each joint is as important as a tidy finish.

Leave it or put it right?
Water getting past a failed seal in a new build reaches walls and floors that are still settling. Resealing promptly protects the new finishes around it. Around Hartley, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether the work is at height. We take all of that into account in your quote.

- We look at why each joint failed, including any movement.
- We remove the failed sealant and clean the joints.
- We make sure the joints are dry and prime them if needed.
- Baths are filled with water, then the new sealant is applied.
