How we handle new build mastic in Fenny Stratford
Developers send us the plot schedule and we work through it. Bathrooms, en suites, kitchens, frames and skirting are sealed ready for handover using the right product for each joint. Common call-outs are for joints pulling apart as timber shrinks and beads laid onto grit and dust from the build, on kitchens, windows & doors and bathrooms & en suites.
For a new home in or near Fenny Stratford, it’s worth checking the sealant early. Gaps at skirtings, shower seals pulling away and missing mastic around frames are common snags.
There’s a 12-month guarantee on every job, large or small.

How the job changes by surface
Show homes
Bathrooms, kitchens and frames in show homes are sealed or resealed to a neat finish to a tidy standard. We’ll plan around viewing times.
Bathrooms and en suites
En suite seals are easy to miss on a snagging list until they leak. Resealing properly keeps water where it belongs.
What happens on the day
A visit follows a simple pattern: we look at the joints together, protect the area around them, do the work and tidy away. It normally takes anything from a few hours to several days, depending on the number of plots. For a job in Fenny Stratford, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- We start by going through the snagging items or plot schedule with you.
- The failed sealant is removed completely, with no layer left behind.
- Joints are vacuumed and cleaned of building dust.
- We prime where needed and apply a sealant suited to each joint.
- We tool every joint neatly and tell you when each area can be used.
Getting ready for the visit
- Where the joints are inside, avoid wetting them before we arrive
- Mention if the joints have been sealed before
- Keep children and pets away from the work area

Why deal with it now?
If you are 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. In an older home around Fenny Stratford, damp from a failed joint can get into timber and plaster, and that’s a much bigger job than renewing the sealant.
Doing several joints on one visit generally makes better use of the time than several visits. We will give you a clear price for the lot.

DIY sealant or a professional job?
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.
What we can’t put right
A few problems are outside what sealant work can do:
- A tray or bath that isn’t properly supported, until it’s fixed
- Structural cracks in walls or ceilings
- Leaking fittings rather than failed sealant
Not sure which it is? You can ring 0345 464 0079 or drop us an email and we’ll tell you honestly.

Keeping the joints in good condition
After the cure time, these simple habits help:
- Keep photos and emails about snagging items
- Resist patching a failed seal with a tube from the DIY shop
- Do not wait for the house to settle if water is getting through
- Report sealant problems to your builder during the snagging period
Keep the bathroom ventilated, especially in the first year. Use the extractor fan or open a window after showers so moisture doesn’t sit on the sealant.
The sooner you deal with untidy or cracking sealant, the less there is to put right. Left alone, a small crack can become a leak in a busy bathroom.

Where are you based?

Why has my new-build shower seal failed already?
New homes dry out and move in their first couple of years, and sealant is often rushed onto dusty, unprimed surfaces. Both lead to early failure.
What information do you need?
Where the job is, what the problem is and roughly how big it is. Photos by email help too.
Will the old sealant be removed?
Yes. We cut out all the old sealant and clean the joint before resealing.
Do I need to be at home?
That depends on where the joints are. Inside work needs someone to give us access, and for outside work we’ll agree access with you when we book.
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.
