New Build Mastic in Lucas Green

- Plot mastic for developers ahead of handover
DIY versus a professional finish
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
How we handle new build mastic in Lucas Green
We work in new homes and on new-build sites across Lucas Green. One shower or a whole phase of plots, the method does not change: remove, clean, prime where needed, then a neat new bead. If you are dealing with smeared, uneven beads picked up at snagging and cracked caulk along new skirting, we can help.
Around Lucas Green, older homes often have timber floors that move through the year, so skirting and threshold joints need a flexible sealant rather than a rigid filler.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

What the job involves on each surface
Show homes
We can refresh show-home sealant that has discoloured or been knocked. We cut it out and reseal neatly.
Skirting and floors
New homes often develop a gap between skirting and floor. A flexible sealant closes it without cracking like caulk.

Looking after it afterwards
Good habits help new joints last longer. Our tips:
- Watch for new gaps as the house dries out
- Record problems with dated pictures
- Don’t seal over failed sealant yourself
- Use the extractor fan every time you shower
Watch the joints as the house settles. Small gaps can appear as the house dries and can be resealed later.
Mould takes hold quickly in sealant that has gaps or lifted edges. Dealing with it before it goes black saves a harder job later.
Common problems we fix in Lucas Green
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.
The most common problems we see are:
- Sealant that never bonded to the surface
- Smeared, uneven beads picked up at snagging
- Worktop and upstand sealant coming away
- Internal frame sealant that has split
If you’ve bought a new home near Brookwood station, the sealant around baths, showers and frames is worth checking in the first year or two.

Leave it or put it right?
DIY kits don’t solve the main problems with new-build sealant: grit, unprimed surfaces and old layers underneath. Cutting out, cleaning and priming are what make the difference. Around Lucas Green, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Doing several joints on one visit normally makes better use of the time than several visits. You will get one clear quote for the whole job.

Questions from Lucas Green
I let a flat near Brookwood station. Can you help?

Is Lucas Green in your area for new build mastic?

How much does new build mastic cost in Lucas Green?
There’s no set price, as it depends on the job: how much there is, what’s there now, how we reach it and what it needs. You will get a clear quote before work begins.
Are you ARBOMaster approved?
Yes. Mr Mastic is an ARBOMaster approved applicator and we are fully insured too.
Why has my new-build shower seal failed already?
New homes dry out and move in their first couple of years, and sealant is often rushed onto dusty, unprimed surfaces. Both lead to early failure.
Do you work for hotels and businesses?
Yes, regularly. Larger jobs can be planned room by room or area by area to suit the site.
Can you match the sealant colour to my new kitchen or bathroom?
That depends on what the joint meets: white or clear for most sanitary joints, colours for worktops, floors and frames. We’ll agree it with you first.
Should I try DIY first?
That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.
