New build mastic in Alloa
Failed shower seals, gaps along the skirting and messy beads are common items on a new-home snagging list. If you are still within the builder’s snagging or warranty period, tell them first. If you are dealing with plot mastic for developers ahead of handover and worktop and upstand sealant coming away, we can help.
Scottish towns like Alloa have older streets and newer estates, with new homes still being built in many. Newer homes need snagging; older ones need their joints renewing.
The work is covered for a year after we finish. If anything is not right with it, email us at info@mrmastic.co.uk.

Should I try it myself first?
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
What we do, step by step
At the end, we look at the finished work together. The work normally takes a few hours for most snagging lists, longer for a run of plots, depending on the size of the job. Parking around Alloa is rarely difficult, though older streets in the centre can be tight. For flats, mention the shared stair or door entry system.
- We look at why each joint failed, including any movement.
- We remove the failed sealant and clean the joints.
- We make sure the joints are dry and prime them if needed.
- Baths are filled with water, then the new sealant is applied.
- We check every joint and leave you with the cure times.
Getting ready for the visit
- Let us know about stairs, lifts or work at height

What affects the cost of new build mastic
Jobs vary more than people expect. The main factors:
- Any working-time requirements on site
- The number of rooms or windows
- How much old sealant there is and how hard it is to remove
- Access and height
A failed joint rarely gets cheaper to fix by waiting. If you’re not sure whether it needs doing, email us at info@mrmastic.co.uk for an honest opinion and a quote.
What we need to know
When you call or email, these details help:
- Where the property is
- What’s wrong with the joints now
- Access, such as stairs, a lift or height
- Roughly how big the job is
We quote each job on its own, so start by telling us what you need. Just email us at info@mrmastic.co.uk with the details and send pictures if you have them.
What sealant work can’t fix
We’d rather tell you now than do work that won’t last, so here’s what sealant can’t put right:
- Baths and trays that move too much for sealant to cope with
- Plumbing faults behind the sealant
- Cracking that points to a structural problem
If you are not sure, just drop us a line at info@mrmastic.co.uk and we’ll give you a straight answer before you book.

What new build mastic looks like in Alloa
Alloa is within about 1 mile of the coast. Plot mastic on new homes near the coast takes more weather than it would inland, so any gaps are best picked up early. Many new homes in Scotland are timber-framed, and as the frame dries and settles, skirting and sealant joints can open up.
If you’ve bought a new home near Alloa station, the sealant around baths, showers and frames is worth checking in the first year or two. In and around Alloa, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

How long should I leave it?
Cure times vary by product and the conditions. We tell you how long to leave it before we go.
What do you need from me for a quote?
The location, the problem and the rough size of the job. If you can, email a few pictures.
Is it normal for sealant to crack in a new home?
A new house dries and settles for a year or two, and sealant is often rushed onto dusty, unprimed surfaces. Both lead to early failure.
Do you work for developers?
Yes. We carry out plot mastic and second-fix sealing for builders and developers. Send us the plot schedule and we’ll quote.
Is there any odour?
There can be a smell while the sealant cures. Ventilation helps.
Aftercare tips
After the cure time, these simple habits help:
- Wipe joints with warm soapy water
- Report sealant problems to your builder during the snagging period
- Keep pictures and emails about snagging items
- Do not wait for the house to settle if water is getting through
Follow the cure time we give you before the area gets wet. Most silicones need around a day.
Report failed sealant to the builder while you’re in the snagging period. After that, putting it right may fall to you, so raise it early.
