New build mastic in Whitley
For builders and developers, we work through plots to the schedule you give us. We seal bathrooms, kitchens, windows, doors and skirting so plots are ready to hand over. If you are dealing with smeared, uneven beads picked up at snagging and internal frame sealant that has split, we can put it right, on windows & doors, kitchens and show homes alike.
If you’ve bought a new home in or near Whitley, the first year or two is a good time to check the sealant. Gaps at skirtings, shower seals pulling away and missing mastic around frames are common snags.
There’s a 12-month guarantee on every job.

How we quote for new build mastic
There’s no set price list, because jobs vary so much. The quote depends on:
- The number of rooms or windows
- When we can work, for business premises
- Whether the work is at height
- Which sealant suits the joint
The cost reflects the work involved, not guesswork. That’s why we ask about the job first.
Helping us quote
Photos by email are helpful but not essential. Please mention:
- Access, such as stairs, a lift or height
- If someone has resealed it before
- Roughly how big the job is
- Whether it’s a home or a business
Call for a quick quote, or email us if that is easier. Describe what needs sealing and we’ll talk you through the work.
What we do, step by step
All our tools and materials come with us in the van, so there’s nothing for you to buy. Once we’ve agreed what’s being done, the area is protected and the work begins. Most jobs take a few hours for most snagging lists, longer for a run of plots. Parking around Whitley is normally easier than in a town centre, but mention any lanes, gates or long drives. If the job is outside, tell us about side access and how high the joints are.
- We go through the snagging list or plot schedule and agree the joints to do.
- Failed or untidy sealant is cut out completely.
- Each joint is cleaned of dust and grit, then primed if required.
- New sealant suited to each joint is applied and tooled neatly.
- Each area is checked and left with its cure time.
Preparing for the visit
- Clear the area around the work
- For indoor joints, keep the area dry beforehand if you can
- Tell us if parking is tricky
How to get a quote

Related advice
Should I try it myself first?
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.
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
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. Homes in smaller places like Whitley can face more weather, and failed outside joints let damp into walls. Indoors, a failed seal lets water into floors and panels as it would anywhere.
Combining jobs into one visit generally makes better use of the time than several visits. You will get one clear quote for the whole job.

Do you need new build mastic in Whitley?
Fresh sealant can be knocked or cut by trades finishing off. A bead disturbed before it has cured may never seal properly.
The most common problems we see are:
- Messy sealant that spoils new finishes
- Joints pulling apart as timber shrinks
- Sealant applied over dusty or wet surfaces
- Sealant work across a run of new homes
Around Whitley, as everywhere, new build mastic is only as good as the preparation behind it.

Looking after it afterwards
After the cure time, these simple habits help:
- Keep pictures and emails about snagging items
- Do not wait for the house to settle if water is getting through
- Do not seal over failed sealant yourself
- Open a window or run the fan after bathing
Keep pictures of the joints and any snagging correspondence with your builder. It helps if anything else comes up during the warranty period.
A failed seal in a new home lets water into joists, plasterboard and ceilings. Catching it early keeps the fix to the sealant and the new finishes intact.
