Mastic sealing in Lochans
We work for building owners, landlords with commercial or block portfolios, managing agents and housing associations. A planned, building-by-building programme often works better than reacting to each complaint, with each block quoted and scheduled in turn. Most enquiries involve no planned programme for sealant and estate-wide sealant that is simply worn out, on external wall and movement joints, communal entrances and stairwells and shopfronts below residential blocks. Searching for sealant specialists in Lochans? We’ve been sealing commercial buildings since 2005, with CSCS-carded applicators.
Around Lochans, outside mastic waits for dry weather and the right temperature. We agree a window with some flexibility.
Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and we explain exactly what that covers when we quote.

How a job runs
Before any cutting starts, the area is protected: tape along each joint edge and covers over finishes, stock and equipment close by. The work itself usually takes anything from a day to a few weeks, depending on the number of buildings and joints, and our waste is bagged and taken away as we go. Travel to smaller Scottish places like Lochans is planned so the job is finished in one visit where possible, which is why we ask for photographs and a full list first. External joints need a dry spell as well.
- We inspect the joints, building by building, and record what has failed and why.
- A fixed quote follows, split by block or building if that suits you.
- The programme is fixed with you, including dates you can pass on to residents or tenants.
- Failed mastic is removed and the faces taken back to sound, dry material.
- Backing rod and primer go in where the joint and the product need them, then new sealant is applied and tooled.
- Each building is checked on completion and the work carries our 12-month guarantee.
Preparing the site
- Make sure the joints can be reached
- Share the asbestos register for older buildings
- Arrange parking or a loading space

Advice
When something else is needed
Honesty saves time and money. New sealant won’t cure:
- Materials that need asbestos testing before work
- Glazing that needs replacing
- Roof leaks, gutters or failed flashings that aren’t sealant joints
If you’re not sure, just call the office on 01277 525 020 or email us and we will give you a straight answer before you book.
What we seal
- External wall and movement joints
- Shopfronts below residential blocks
- Communal entrances and stairwells
- Window and door perimeters on blocks
- Communal kitchens and washrooms
- Balcony and threshold joints
What happens if it’s left?
Resealing ahead of leaks keeps it to a maintenance task. Once water has tracked in, the repair list grows, and the complaints come with it. Exposed buildings in Scotland take a lot of weather, and for a smaller place like Lochans, a repair visit takes planning, so it’s better to act early.
The product called for affects the cost, as does the preparation each joint needs, from cutting out to priming and backing rod. Access, phasing and site requirements come into it too.

Aftercare for building managers
For the best life from the joints:
- Avoid piecemeal callouts where you can
- Prioritise elevations facing the weather
- Ask residents or tenants to report leaks and draughts early
- Log resealing dates block by block
Keep records of when each building was resealed. That makes future programmes easier to plan and gives you a history.
Left open, joint edges in render, brick or frames can deteriorate. Then the edges may need repairing first.

What else we do in Lochans
Common problems we fix in Lochans
We often find joints filled solid with no backing rod so the mastic is bonded on three sides. It can’t stretch properly and splits as the building moves.
Any of the following is a good reason to get the joints checked over:
- Communal area joints that look neglected
- Estate-wide sealant that is simply worn out
- Cracked, hardened mastic round windows on a block
- Leaks at window and door perimeters
Buildings close to stations like Stranraer station, 2.9 miles north of Lochans, are often flats over shops, with frame mastic to keep sound.

Your questions answered
Will you take on work at estates like Castle Kennedy Industrial Estate, close to Lochans?
Yes, sites like Castle Kennedy Industrial Estate are within our area, along with the rest of Lochans. Send details of the unit and the work through our quote form for a quick quote.
Is a smaller place like Lochans outside your area?
No. Small places get the same service as large ones. We cover the whole of Scotland. We plan jobs in smaller places so return trips are kept to a minimum.
How do you handle work on occupied blocks?
Occupiers stay in the building throughout. We flag any areas that need internal access well before the dates so it can be arranged.
Can you seal joints high up on a block?
It depends on the building. How upper joints are reached is agreed before work is booked so there are no surprises.
How many days will you need on site?
It depends on the scope, but the work normally takes a day or two for a single block, longer for an estate programme. Larger or phased jobs take longer, and we will give you a timescale with the quote.
What paperwork can you provide?
Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote. We are CHAS accredited and a Constructionline member.
Can weather delay the job?
For external joints, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Internal work is rarely affected.
How the job changes by surface
Estate-wide resealing programmes
Housing associations and agents often manage many similar blocks. Each block is priced and scheduled in order.
External movement joints
External movement joints take up expansion and contraction. Once that sealant goes, rain can reach the wall.
Mastic sealing in Lochans: the local picture
The sea is no more than about 3 miles from Lochans. Sea-facing elevations take driven rain and salt, and their mastic shows it before the sheltered sides do, so it’s worth inspecting those sides more often. Being in the west of Scotland, Lochans gets more rain than eastern areas. Frame mastic on weather-facing sides tends to fail first. Outside mastic goes on in dry spells, with some flexibility in the programme.
Landlords with units on estates such as Castle Kennedy Industrial Estate (to the north of Lochans) can bring frame, door and external mastic across several units into one programme.
