About our new build mastic in Hook
New homes move as they dry out. Timber dries and shrinks, and baths and trays settle, so sealant that was laid quickly before handover often cracks. If you are dealing with untidy sealant flagged on a snagging list and gaps opening as the house dries out and settles, we can help, whatever the surface.
If you’ve bought a new home in or near Hook, the first year or two is a good time to check the sealant. Common snags include open skirting joints, lifting shower seals and gaps around frames.
Big or small, it’s backed by our one-year guarantee in Hook and across Hampshire.

What happens if it’s left?
The builder is generally the first port of call while the snagging or warranty period runs. If it keeps failing or isn’t dealt with, we can reseal it properly. Homes in smaller places like Hook can face more weather, and failed outside joints let damp into walls. Inside, a split seal lets water into floors and panels just as it would anywhere.
We do not show prices on the website, because the cost depends so much on the job itself. Call for a quick quote.

DIY versus a professional finish
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
Keeping the joints in good condition
So the new joints stay in good condition:
- Raise failed sealant with the developer while you’re covered
- Ventilate bathrooms well, especially in the first year
- Get a leaking seal dealt with right away
- Clean sealant with mild detergent, not abrasives
Avoid standing on the rim of the bath or the edge of the tray. If a bath or tray moves when you stand in it, get it looked at.
Mould takes hold quickly in sealant that has gaps or lifted edges. Resealing before mould gets in saves a harder job later.

Hook: your questions answered
Do you cover Hook for new build mastic?
Yes. We work across London and the South East, and Hook is part of that. You can phone 0345 464 0079 or drop us an email and tell us what needs doing.
I let a flat near Hook station. Can you help?
Yes, we work for letting agents and landlords. You can call 0345 464 0079 or email us with the address and a few details, and we will give you a fixed price before work begins.
Can you match the sealant colour to my new kitchen or bathroom?
White and clear are the most common, but sealant comes in other colours too. We choose one to suit the room before we begin.
Can you reseal over the builder’s sealant?
No. The old sealant is cut out fully, then clean and prime the joint, and a new bead applied.
Will you leave a mess?
Not at all. We work neatly, protect the area around the joints and tidy up afterwards.
Which products do you use?
It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.
What should I tell you?
Only a few details: the address or postcode, what’s wrong and any access issues. After that, simply call 0345 464 0079 or drop us an email.
Can you do plot mastic on a new development?
Yes. We take on second-fix sealant work across new plots. Good preparation keeps snagging to a minimum.
Do you need new build mastic in Hook?
Sealant applied onto damp surfaces does not bond well. On a busy site, joints are not always given time to dry before the sealant goes on.
Signs it’s time to call us include:
- Gaps between new skirting and floors
- Untidy sealant flagged on a snagging list
- Shower seals failing in the first year or two
- Cracked sealant around new window and door frames
If you’ve bought a new home near Hook station, the sealant around baths, showers and frames is worth checking in the first year or two.
Questions to ask before you book
- How the joint is cleaned and prepared
- When the joint can take water or movement
- What happens if they find a problem under the old sealant
- Are they insured?
