How we handle mastic sealing in Dogslacks
Treatment starts with a proper look: which joints have failed, why, and whether sealant is the right answer. Old mastic is removed entirely, the faces prepared, primer used where the maker specifies it and new sealant tooled in and backing rod used wherever a joint is deep. We work on balcony and threshold joints, window and door perimeters on blocks and shopfronts below residential blocks, and the usual reasons a site gets in touch are complaints coming in block by block and patchy repairs in mismatched sealant. One point of contact handles commercial sealant work in Dogslacks from the first photographs to the final walk-round, whether it’s one building or several.
Around Dogslacks, outside mastic waits for dry weather and the right temperature. Programmes allow for the weather.
The 12-month guarantee covers our workmanship: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

After the work
A few simple habits keep the new joints working:
- List the paperwork your organisation requires when you send details
- Reduce knocks to communal area joints
- Log resealing dates block by block
- Prioritise elevations facing the weather
Encourage occupiers to report water or draughts at frames. A quick report keeps a small repair small.
Joints on a building age together so a single failure is a sign to check the rest. A planned reseal saves repeated visits.

Commercial clients in Dogslacks
Blocks and communal areas make up much of the work for housing associations and agents. Work can be phased so residents and staff keep access throughout, and each stage is agreed with your contact.
Hotels, schools, healthcare sites, offices and retail units come to us directly as well. We plan around the way the building is used, so the building keeps working while we do.
What we can’t put right
A proper diagnosis includes knowing what sealant can’t do. You will hear from us if the cause turns out to be one of these:
- Misted or failed double-glazed units
- Leaks through the frame itself rather than the perimeter
- Cracked or crumbling render, brick or stone at the joint edges (we’ll tell you if so)
If you are not sure, just give us a call on 01277 525 020 or email us and we’ll give you a straight answer.

Questions we’re asked in Dogslacks
Is a smaller place like Dogslacks 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.
Do you take on block-wide or estate-wide mastic work in Dogslacks?
Yes. Portfolio-wide programmes are a regular request. Residents are given notice through you, and the work moves building by building.
Do you supply RAMS and insurance details?
We are CHAS accredited, a Constructionline member and carry public liability insurance. For specific documents, tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote.
When can the area be used after sealing?
The product and site conditions decide that. Some take light use quickly, others need longer to cure, so we’ll confirm the curing time on the day.
What about access for upper-floor joints?
Every block is different. We agree access with you at quote stage so there are no surprises.
Do you guarantee the mastic work?
Our workmanship carries a 12-month guarantee and we hold public liability insurance.
Does weather matter for sealant work?
For external joints, yes. The joint has to be dry and within the product’s temperature range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.
Common problems we fix in Dogslacks
Frames, panels and masonry expand and contract through the year, and the sealant takes up that movement. If the joint or the product wasn’t suited to the movement, it splits and fails early.
Things that usually lead to an enquiry:
- Estate-wide sealant that is simply worn out
- No planned programme for sealant
- Draught complaints from residents or tenants
- Leaks at window and door perimeters
If you are responsible for a building such as Middlebie Parish Church And Churchyard, frame and door mastic needs the same attention as any other property.

How a job runs
Site rules come first: signing in, inductions and any permit to work. Once we are cleared to begin, we take the joints in the sequence agreed with you, and each area is checked before we leave it. Travel to smaller Scottish places like Dogslacks is planned so the job is finished in one visit where possible, which is why we ask for photos and a full list first. External joints need a dry spell as well.
- We inspect each building and record the joints that have failed.
- The quote is fixed and split as suits you.
- Dates and areas are agreed so occupiers can be told.
- Old mastic is removed and the joint faces prepared.
- New sealant goes in with backing rod and primer where needed.
- We check the finished work and confirm the guarantee.
What we need from you

Site staff or a sealant specialist?
A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.
