New-build mastic & snagging in Reading, Wokingham
We cover Reading for plot mastic for developers and snagging failed sealant in new homes. Old sealant removed completely, joints prepared properly and a one-year guarantee.
- Gaps opening as the house dries out and settles
- Smeared, uneven beads picked up at snagging
- Gaps behind new kitchen upstands
Aftercare tips
Once the sealant has cured, a few habits help it last:
- Record problems with dated photos
- Get a leaking seal dealt with right away
- Clean sealant with mild detergent, not abrasives
- Check bath and shower seals every few months as the house settles
Watch the joints as the house settles. Small gaps can appear as the house dries and can be resealed later.
A failed seal in a new home lets water into joists, plasterboard and ceilings. Early resealing keeps the job small and the new finishes intact.
How we handle new build mastic in Reading
Some owners wait for the first year’s movement before having joints redone. For small cosmetic gaps, that is reasonable, but a failed shower or bath seal shouldn’t wait. We work on skirting & floors, plot handovers and windows & doors, and people most often call us about frame joints opening as the plaster dries and gaps behind new kitchen upstands.
Commercial units around a large town like Reading usually have concrete floors with joints that need filling and resealing as they wear. Homes need the same attention on a smaller scale, from skirting joints to shower seals.
You get a 12-month guarantee, the same in Reading as everywhere else we work.

Can I do it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Do you work for letting agents?
Yes, often. We can quote for several properties at once, and between tenancies is a good time for the work.
Will it make a mess?
No. We work neatly, protect the area around the joints and tidy up afterwards.
When is the best time to reseal in a new build?
Any seal that is leaking should be redone right away. Cosmetic gaps can wait until the first year or two of movement has passed.
How long does new build mastic take?
Typically it takes a few hours for most snagging lists, longer for a run of plots. Larger jobs naturally take longer, and we will say how long yours will take.
Can I add another job to the visit?
Yes. Several rooms, windows or areas can go on one quote.

Advice
Should I try it myself first?
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

Quotes for new build mastic in Reading
We quote each job individually. This is what makes a difference:
- Any working-time requirements on site
- The type of sealant required
- Whether the work is at height
- The number of rooms or windows
Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. You’ll know the price before we begin.
What we need to know

What happens if it’s left?
If you’re still in the builder’s snagging or warranty period, ask them to put it right first. If it keeps failing or is not dealt with, we can reseal it properly. In a large rental market like Reading, tired sealant leads to tenant complaints about mould, damp and leaks. It’s simpler to sort between tenants than in the middle of a let.
Leaving a failed joint normally makes the job bigger, not smaller. If you’re not sure whether it needs doing, phone 0345 464 0079 or email us for an honest opinion and a quote.
