FAQs for Hampstead Norreys

What do you need from me for a quote?

Sometimes, a little. Any smell clears as the sealant cures, and ventilation helps.
Do you have insurance?
Yes. We are fully insured, and we’ve been doing sealant work for more than 20 years.
Should I go to my builder first?
Start with your builder while their snagging or warranty period runs. If that doesn’t work out, we are happy to quote and our work is guaranteed for a year.
Where are you based?
We are based in Crawley, and we work across South East England, London and Scotland.
Is it normal for sealant to crack in a new home?
Lots of new homes see sealant crack early as timber and plaster dry out. Rushed application on dusty surfaces makes it worse.
About our new build mastic in Hampstead Norreys
Our new-build work comes in two parts: plot mastic for developers, and putting right failed sealant for people who’ve bought a new home. In both, preparation makes the difference, because that’s what rushed new-build sealant generally lacks. If you are dealing with sealant that never bonded to the surface and skirting joints opening in the first winter, we can put it right.
Around Hampstead Norreys, older homes often have timber floors that move through the year, which is why skirting and threshold joints need a flexible sealant, not filler.
The work is covered for a year after we finish. If anything is not right with it, ring 0345 464 0079 or email us.

What else we do in Hampstead Norreys
For landlords and businesses
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.
Housing providers, facilities teams and property managers book us too in Hampstead Norreys and across West Berkshire. Several sites can go on one quote, and we’re fully insured for the work.
DIY versus a professional finish
A DIY attempt does not rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
Why deal with it now?
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. Where a wall is exposed, as many are in small places like Hampstead Norreys, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you are unsure, phone 0345 464 0079 or send us an email and we will give you an honest view and a quote.

How we quote for new build mastic
The quote reflects the job in front of us. We look at:
- The product the joint needs
- Any mould that needs treating
- The number of rooms or windows
- Any working-time requirements on site
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed. Call for a quick quote and we’ll explain what it covers.
What we need to know
The more you tell us, the more accurate the quote. When you ask for a quote, tell us:
- The type of property
- What’s wrong with the joints now
- How we’d reach the joints
- Where the property is
There’s no standard price list, as no two jobs are quite the same. Instead, your job gets its own clear quote. To arrange one, call 0345 464 0079 or drop us an email.
Do you need new build mastic in Hampstead Norreys?
Baths and trays settle under load once the home is lived in. A bath sealed empty drops slightly when filled, straining the joint and can tear.
Keep an eye out for these signs:
- Sealant work across a run of new homes
- Gaps between new skirting and floors
- Cracked sealant around new window and door frames
- Untidy sealant flagged on a snagging list
Whether the job is in Hampstead Norreys itself or nearby, the right material for each joint matters as much as a neat finish.
What to look for in a quote
- What the cure time is
- What insurance they hold
- How the surfaces are prepared before sealing
- How much experience the applicator has
