Mastic sealing for commercial buildings in Portmahomack
Our clients include managing agents, property factors in Scotland, housing associations and landlords with block or commercial portfolios. Many prefer a planned programme to one-off visits and we quote and schedule each building in turn. Most enquiries involve a mix of products and colours from past repairs and complaints coming in block by block, on shopfronts below residential blocks, window and door perimeters on blocks and communal entrances and stairwells. Most enquiries from Portmahomack start with one failed joint and grow into a wider look at the building: we look at the rest while we’re there and tell you what we find.
In smaller Scottish places like Portmahomack, managed property is mostly small blocks, sheltered housing, hotels and community buildings. Exposed walls take Scottish weather hard, and frame mastic shows it first.
We stand by our work: 12 months, guaranteed. That covers our preparation and application.

When to call us in Portmahomack
Topping up old mastic is a common shortcut. New silicone has nothing to grip on old silicone, so these repairs rarely last.
It’s worth sending us details if you spot any of the following:
- Brittle perimeter mastic across a building
- Occupiers reporting cold air round windows
- Damp patches beside frames
- Mastic failing across several blocks on an estate
For a building around Portmahomack, a look at every elevation first shows which joints need renewing now and which can wait.

Honesty saves time and money. Fresh joints won’t solve:
- Frames that are rotten, warped or broken
- Glazing that needs replacing
- Leaks from above rather than through a joint
If in doubt, call 01277 525 020 or send photos by email and we will say what we think.

Advice
Why act early in Portmahomack
Adding sealant to cyclical maintenance is an easy win. Leaving it until there’s a leak turns it into reactive work with less control over timing. In Scotland, wind-driven rain finds a failed joint quickly, and for a smaller place like Portmahomack, a repair visit takes planning, so it’s better to act early.
Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.
What you get with us
- Fully insured, including public liability cover
- Colours chosen to suit frames, cladding or finishes where possible
- Colour agreed before work starts
- Products installed to the manufacturer’s instructions

FAQs: Portmahomack
Do you take on block-wide or estate-wide mastic work in Portmahomack?
Yes, we quote for single buildings and for programmes across several blocks. Residents are given notice through you, and the work moves building by building.
Is Portmahomack off your patch?
No. Places such as Portmahomack are covered as much as the big towns. Every Scottish council area is within our area. We plan jobs in smaller places so return trips are kept to a minimum.
When can the area be used after sealing?
The product and site conditions decide that. Some products skin over quickly but need longer to cure fully, so we’ll confirm the curing time on the day.
How do you reach windows on upper floors?
We talk through access for each building when we quote. Tell us the number of storeys and whether scaffold or other access is planned and we will confirm the approach in the quote.
How long does a typical visit take?
It depends on the scope, though a typical visit usually takes anything from a day to a few weeks, depending on the number of buildings and joints. For bigger or phased jobs, we will set out a timescale with the quote.
Is mastic sealing guaranteed?
A 12-month guarantee covers our work. It applies to our workmanship rather than damage or problems with the frames.
Is it fine to apply new sealant on top of old?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, since fresh sealant will not bond reliably to aged material.

After the work
Cleaning and maintenance staff play a part too. Share these points with them:
- Include mastic in your cyclical inspections
- Check the asbestos register before any old mastic is disturbed
- Plan resealing building by building rather than complaint by complaint
- Encourage occupiers to report problems at frames
Include sealant in planned building inspections. Check for splits, open joints, brittle mastic and lifting edges and record where they are.
The longer failed joints are left, the more likely the substrate edges break up. Then the edges may need repairing first and the job grows.
