New-build mastic & snagging in Howgate, Midlothian
New build mastic across Howgate and nearby, with every bit of old sealant taken out first.
- Sealant work across a run of new homes
- Gaps between new skirting and floors
- Messy sealant that spoils new finishes
How we handle new build mastic in Howgate
Building dust is behind a lot of failed new-build sealant. Each joint is cleaned of dust and primed where the product calls for it, so the sealant actually sticks instead of bonding to the dust. Typical jobs include cracked caulk along new skirting and messy sealant that spoils new finishes, across plot handovers, bathrooms & en suites and skirting & floors.
For a place like Howgate, the journey and access are planned in advance. Outdoor plot mastic needs dry weather, but indoor floor and skirting joints can be sealed whatever the forecast.
Your job is guaranteed for a year, as with all our work.

Quotes for new build mastic in Howgate
Some jobs are bigger than they look, and some smaller. What affects the quote:
- Which sealant suits the joint
- How easy the joints are to reach
- The number of rooms or windows
- The number and length of the joints
Commercial jobs are quoted on the same basis as homes: the amount of work, how we reach it and what it needs, plus any working-time requirements on site. Ask us for a quote and we will go through it with you.
Asking for a quote
There’s no need for technical detail. Just tell us:
- What the problem is, such as mould, gaps, leaks or cracking
- The type of property
- Any previous sealing or DIY work
- How many joints, rooms or windows are involved
For a quote, email us at info@mrmastic.co.uk with the location and a short description of the problem. We will give you a clear quote before any work starts.
Looking after it afterwards
No joint lasts for ever, but care makes a real difference. A few tips:
- Use the extractor fan every time you shower
- Wait for the cure time before using a resealed shower
- Resist patching a failed seal with a tube from the DIY shop
- Avoid scourers and strong chemicals on sealant
Follow the cure time we give you before the area gets wet. Silicone is normally left for about a day before water reaches them.
Mould takes hold quickly in sealant that has gaps or lifted edges. Resealing before mould gets in keeps the job straightforward.

New homes and floors in Howgate
Timber frame is common in newer Scottish homes, and as the frame dries and settles, skirting and sealant joints can open up.

What happens if it’s left?
A tube of sealant from the DIY shop will not fix the cause: grit, unprimed surfaces and old layers underneath. Cutting out, cleaning and priming are what make the difference. Around Howgate, water from a failed joint in an older stone home can soak into timber and plaster, which is a far bigger job than the sealant.
No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all play a part.

Common problems we fix in Howgate
Baths and trays settle under load once the home is lived in. A bath sealed empty drops slightly when filled, straining the joint.
Any of these means the joints need attention:
- Plot mastic for developers ahead of handover
- Worktop and upstand sealant coming away
- Cracks appearing as a new home settles
- Untidy sealant flagged on a snagging list
In and around Howgate, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.
Questions to ask before booking
- What product goes in the joint
- How much experience the applicator has
- How the joint is cleaned and prepared
- Whether they’re fully insured
