What the job involves on each surface
Windows and doors
External mastic around new windows and doors is sometimes rushed or missed. We reseal it with a weatherproof, flexible sealant.
Skirting and floors
Floors and skirting move as the house dries and the heating runs. We use a flexible product rather than caulk.
About our new build mastic in Marden Ash
Some new-home owners let the house settle before resealing. For small cosmetic gaps, that is reasonable, but a seal that is letting water through needs doing now. If you are dealing with leaking shower tray seals in a new home and internal frame sealant that has split, we can help, on plot handovers, show homes and kitchens alike.
Around Marden Ash, older homes often have timber floors that move through the year, which is why skirting and threshold joints need a flexible sealant, not filler.
All our work is covered by our 12-month guarantee.

DIY sealant or a professional job?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.

Your questions about new build mastic in Marden Ash
Is new build mastic in Marden Ash guaranteed?
All our work, in Marden Ash and everywhere else, comes with a 12-month guarantee. We’re also fully insured and ARBOMaster approved.
Is Marden Ash within the area you cover?
Yes, smaller places are covered as well as towns. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Can tenants book the work?
Yes, but check with your landlord or agent first. Many landlords are glad to have it sorted.
Do you take out the old sealant first?
Yes. We cut out all the old sealant and clean the joint before resealing.
Why does sealant fail so quickly in new builds?
There are normally two causes: the house moving as it dries, and sealant that never bonded properly. Cutting it out and resealing properly fixes both.
Can you work on commercial sites?
Yes. Hotels, offices and other businesses use us.
Is it worth resealing while the house is still settling?
Where water is getting through, don’t wait. Small gaps that are just cosmetic can be resealed once movement has slowed.
Which products do you use?
Quality sealants from brands including Arbo and Everbuild, picked for each joint. We explain the product when we quote.
Why act early in Marden Ash
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. Where a wall is exposed, as many are in small places like Marden Ash, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.
Why Marden Ash clients choose us
- Anti-fungal sanitary silicone in wet areas

The process
Every visit runs the same way: we check the joints, mask and protect the surrounding surfaces, do the work and tidy away.

For outside work, also let us know about exposed walls and any outbuildings involved.
- First we work through your snagging list or plot schedule with you.
- The old bead comes out in full, with no layer left behind.
- Surfaces are cleaned of building dust and primed where needed.
- We apply a sealant that suits each joint and tool it to a neat finish.
- We check every joint and tell you how long each needs to cure.
Preparing for the visit
