New build mastic in Redenham
We carry out plot mastic and second-fix sealing for builders, and snagging reseals for new-home owners. In both, preparation makes the difference, because that’s what rushed new-build sealant generally lacks. If you have joints pulling apart as timber shrinks and sealant work across a run of new homes, we can put it right, on skirting & floors, windows & doors and plot handovers alike.
Older homes in small places like Redenham often have timber floors that move with the seasons, so skirting and threshold joints need a flexible sealant rather than a rigid filler.
A 12-month guarantee comes as standard, so you’re covered after we have gone.

What we do, step by step
There’s no need to move everything out, just the space around the work. We protect the rest, and the work takes a few hours for most snagging lists, longer for a run of plots in most cases. In a small place like Redenham, access is usually the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We look at why each joint failed, including any movement.
- We remove the failed sealant and clean the joints.
- Joints are dried and primed where the product calls for it.
- Baths are filled with water, then the new sealant is applied.
- We check every joint and leave you with the cure times.
How to prepare
- Mention any tricky access
- Tell us if parking is tricky
- Let us know about earlier repairs to the joints

When it isn’t the sealant
New sealant cannot fix everything, and we’d rather say so up front. Sealant won’t put right:
- Structural cracks in walls or ceilings
- Your warranty claim itself, which is between you and the builder
- Cracked trays, tiles or worktops
If you’re not sure, just phone 0345 464 0079 or send us an email and we will give you a straight answer.
Surfaces we seal

- Windows & doors
- Show homes
- Bathrooms & en suites

Redenham: your questions answered
Can you help a landlord with a rental near Andover station?
Yes, landlords and agents are among the people we work for. You can ring 0345 464 0079 or send us an email with the details for a clear quote.
Do you cover Redenham for new build mastic?
Yes. We work across London and the South East, and Redenham is part of that. Just call 0345 464 0079 or send us an email with a few details of the job.
Is there any odour?
Sometimes, a little. Any smell clears as the sealant cures, and ventilation helps.
Can I send you my snagging list?
Yes. Send us the sealant items on the list, with photos if you can. We’ll tell you if anything on it isn’t a sealant job.
Do you take out the old sealant first?
Yes. All of the old material is cut out and the joint cleaned.
Can you do several jobs on one visit?
Yes. Tell us about everything you’d like done.
Where is Mr Mastic based?
We work from Crawley. Our applicators cover Redenham.
Will it make a mess?
No. The area is protected while we work and cleaned up afterwards.
DIY versus a professional finish
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.
Landlord and commercial work in Redenham
Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.
We regularly work with letting and managing agents. Send the address, what’s needed and the access arrangements.
Signs you need new build mastic in Redenham
Sealant applied onto damp surfaces does not bond well. On a busy site, joints are not always given time to dry.
The most common problems we see are:
- Second-fix sealing on new plots
- Cracks appearing as a new home settles
- Internal frame sealant that has split
- Messy sealant that spoils new finishes
For new homes near Andover station, it’s worth checking the sealant early, while snags are still fresh.
What to look for in a quote

- The length of the guarantee
- Who turns up on the day

Surface by surface
Kitchens
Worktop, upstand and sink joints in new kitchens often get a hurried bead. We remove it and reseal with a kitchen-suitable sealant.
Show homes
Show homes need sealant that looks right from day one. Every bead is neat and coloured to suit the room.
Why deal with it now?
A failed shower or bath seal in a new home lets water into floors and walls that are still drying out. Dealing with it early keeps the damage away from ceilings, floors and finishes. In a small place like Redenham, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Combining jobs into one visit is generally more efficient than separate visits. You will get one clear quote for the whole job.
What you get with us
- Arbo and Everbuild products
- Any old sealant cut out fully, not covered over
