Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
Should maintenance staff do it?
Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
About our mastic sealing in Altnaharra
Our clients include managing agents, property factors in Scotland, housing associations and landlords with block or commercial portfolios. A planned, building-by-building programme often works better than reacting to each complaint, with each block quoted and scheduled in turn. If you have draughts at frames across a block and the same joint failures repeated across a portfolio, we can help, whatever the surface. A specialist sealant contractor works differently from a general builder: on jobs in Altnaharra, preparation and product choice get the time they need.
For buildings around Altnaharra, we group the work to keep travel and visits down. Send addresses and photographs for a quote covering the batch.

Why act early in Altnaharra
Reacting to every complaint means sending someone out block by block. Planned resealing covers a whole building or estate in one go, under a single quote and a single programme. Renewing every failing joint on one visit is the sensible approach for a place like Altnaharra. Photos of each area help us quote the whole job.
The specified product makes a difference, and so does the preparation. Access, phasing and site rules also count.

Common questions from Altnaharra clients
Will you price a mastic programme across our Altnaharra portfolio?
Yes. Portfolio-wide programmes are a regular request. Residents are given notice through you, and the work moves building by building.
What documents will you need to give us for a job in Altnaharra?
Whatever your site asks for, from RAMS to CSCS details, is confirmed when we quote. We are CHAS accredited and a Constructionline member, with £5m public liability insurance and CSCS-carded applicators.
Is it fine to apply new sealant on top of old?
No. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.
Can people stay in the building while you reseal?
Occupiers stay in the building throughout. If any flats or units need access, we will tell you in advance so you can arrange it with occupiers.
Are you CHAS accredited and on Constructionline?
Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.
Can you take on resealing for a block portfolio?
Yes, that’s exactly who this service is for. Buildings are scheduled in turn with dates agreed in advance.

Yes. Altnaharra falls within our area, and the simplest way to start is to ring 01277 525 020 or use the quote form.
Surface by surface
Tenement and older buildings
Stone needs a neutral-cure product and we choose accordingly.
Window and door perimeters on blocks
On most blocks, the frame-to-wall joint is where failure shows first. Old perimeter mastic is removed, the joint prepared and new sealant tooled in.

Our process
Before any cutting starts, the area is protected: tape along each joint edge and covers over finishes, stock and equipment close by. On site, the work normally takes a day or two for a single block, longer for an estate programme, and we clear our waste as we work. Travel to smaller Scottish places like Altnaharra 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 check the asbestos register for older buildings and look at the joints.
- The products and programme are set out in a fixed quote.
- Failed mastic is removed completely.
- Joint faces are cleaned, backed and resealed.
- We finish each building before moving to the next.
Before we start on site
- Let building users know which areas are affected
- Have the specification and drawings to hand
- For older buildings, check the asbestos register before work

Advice
When to call us in Altnaharra
Previous repairs often sealed new mastic over old. 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:
- Worn sealant at communal door frames
- Occupiers reporting cold air round windows
- Water getting in round frames after rain
- Failed external movement joints
For a building around Altnaharra, a look at every elevation first shows which joints need renewing now and which can wait.
Before you book anyone
- Their plan for phasing and protecting the area
- Whether old or failed sealant will be cut out, not overlaid
- The terms of the workmanship guarantee
- Proof of insurance
When it isn’t the sealant
Not every problem is a sealant problem, and we’d rather tell you before you spend money. It won’t fix:
- Roof leaks, gutters or failed flashings that aren’t sealant joints
- Substrate edges that need repairing first
- Broken glass or failed sealed units
Not sure which it is? You can give us a call on 01277 525 020 or email us and we’ll tell you honestly.
