New Build Mastic in Stroude
New-build sealant joints in Stroude need attention? We cut out the old, prepare the joints and apply the right sealant, with a one-year guarantee.
- Second-fix sealing on new plots
- Gaps between new skirting and floors
- Shower seals failing in the first year or two
What happens if it’s left?
A tube of sealant from the DIY shop will not fix the cause: dust, no primer and old sealant left in the joint. Proper removal and preparation are what make it last. In a small place like Stroude, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Every job is a little different, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all play a part.

New build mastic in Stroude
Some new-home owners let the house settle before resealing. That makes sense for small gaps that are just cosmetic, but a seal that is letting water through needs doing now. If you have gaps behind new kitchen upstands and plot mastic for developers ahead of handover, we can put it right.
Around Stroude, older homes often have timber floors that move through the year, so skirting and threshold joints need a flexible sealant rather than a rigid filler.
Each job carries a 12-month guarantee, large or small.

Looking after it afterwards
Aftercare is simple:
- Don’t wait for the house to settle if water is getting through
- Look at the sealant regularly in the first couple of years
- Raise failed sealant with the developer while you are covered
- Ventilate bathrooms well, especially in the first year
Avoid standing on the rim of the bath or the edge of the tray while the sealant cures. If a bath or tray moves when you stand in it, get it looked at.
Leave a failed new-build seal and water can reach the floor and the ceiling below. Early resealing keeps the job small and protects the rest of the house.

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 work itself takes anything from a few hours to several days, depending on the number of plots from start to finish.

Everything for the job comes with us, so a second trip is avoided where possible.
- We go through the snagging list or plot schedule and agree the joints to do.
- Failed or untidy sealant is cut out completely.
- We clean off dust from the build and prime the surfaces where the product needs it.
- A sealant chosen for each area goes in and is tooled smooth.
- Finally, each room is checked and you are given the cure time.
How to prepare
- Plan for the work area to be out of bounds to pets and children

The first winter with the heating on dries a new home quickly. Skirting, frames and worktops pull away slightly and cracks appear in the sealant.

- New-build shower sealant that has already split
- Beads laid onto grit and dust from the build
- Gaps opening as the house dries out and settles
- Untidy sealant flagged on a snagging list

I let a flat near Virginia Water station. Can you help?

Are you insured?
Yes. We are fully insured, with over 20 years’ experience in sealant work.
What should I tell you?
Just the basics: the address or postcode, what’s wrong and any access issues. After that, simply ring 0345 464 0079 or email us.
Do you work for hotels and businesses?
Yes. We have worked for hotels, offices and other businesses and we are fully insured.
Should I try DIY first?
It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.
Can new sealant go on top of the old bead?
No. Sealing over old sealant looks fine for a few weeks, then lifts. All the old sealant comes out before any work starts.
Can I send you my snagging list?
Yes. Send the list and a few pictures of the sealant items, and we will quote. We will flag anything that needs another trade.
Can I do it myself?
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so just mention it when you contact us.
If you do try it yourself, take your time over the 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.
