What the job involves on each surface
Bathrooms, en suites and washrooms
In bathrooms and washrooms, an anti-mould sanitary silicone goes around every fitting. Joints are cleaned, sealed and tooled neatly.
Window and door perimeters
Gaps around frames have to be within the sealant’s range. Gaps outside the product’s range are raised with the site team before sealing starts.
Construction mastic in Altnaharra
Mastic follows everyone else, which means it absorbs every delay upstream. The sequence is set with the site team and updated as plots or floors are handed over. That keeps the work right first time and saves rework. The enquiries we see most involve cracks opening in caulked internal joints and bath and shower joints scraped during the final clean, on internal decorators’ caulk, brick and block movement joints and window and door perimeters. Facilities teams, main contractors and managing agents in Altnaharra tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.
For a site around Altnaharra, we plan the mastic in as few trips as the programme allows. Send drawings, photographs and the programme so everything needed arrives on the first day.
We stand behind the joints we seal: 12 months, guaranteed. That covers our preparation and application, and we come back if anything isn’t right.

Do you need construction mastic in Altnaharra?
Shrinkage and settlement in the first months put new joints under strain. Materials lose construction moisture and shrink. Choosing the right product for each joint reduces that.
It’s worth sending us details if you spot any of the following:
- Perimeter gaps outside the sealant’s range
- Mastic snags holding up handover
- Frame perimeters left unsealed or poorly sealed
- External joints sealed in damp or cold conditions that are now failing
Work at a hotel such as Altnaharra Hotel (less than half a mile south-east of Altnaharra) tends to be programmed around bookings, mastic included.
Before you book anyone
- Are they CHAS accredited or on Constructionline?
- How the existing material will be dealt with
- How the joint faces will be prepared and primed
- How they handle RAMS and site documents
On site: what to expect
The first thing on site is a walk round with your contact, to confirm the scope, the order of work and any areas we must keep clear. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. Jobs near Altnaharra are often grouped with others in the same area, to make the most of each trip. Let us know if your dates have any give.
- We price from the drawings, specification and programme you send.
- We return a fixed quote that ties the mastic package to your programme.
- You tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we confirm it with the quote.
- We seal each plot or floor as it’s released to us.
- Every joint is prepared, set to depth and sealed with the specified product.
- Before handover, snags are dealt with and the package is signed off under our 12-month guarantee.

- Explain the parking and delivery arrangements
- Point out any areas we must not close

Quoting for work in Altnaharra
Quotes vary with the job. It mainly depends on:
- The site’s rules and procedures
- Distance, for remote addresses
- The size and state of each joint
- How much existing material needs removing
The specified product makes a difference, and so does the preparation, from cutting out to priming and backing rod. Access, phasing and site requirements come into it too.
Details that help us quote
Diagnosis starts before we arrive. Let us know:
- The postcode of the building
- A wide shot and a close-up of the area
- Any dates the work must fit around
- Approximate linear metres or a joint schedule
Every job follows the same four steps: send details, get a quote, we seal, guaranteed. The first step is to call the office on 01277 525 020 or email us with what you know.
When something else is needed
A few problems need another trade or a different fix, and we say so rather than covering them up:
- Damage to finishes by other trades after we’ve sealed
- Approving fire stopping as compliant
- Defective windows, doors or glazing units (the supplier or installer’s job)
Not sure which it is? You can give us a call on 01277 525 020 or email a schedule or drawings and we’ll tell you honestly before you book.
Surfaces we seal
- Cladding and panel joints
- Floor and skirting junctions
- Brick and block movement joints
- Window and door perimeters
- Internal decorators’ caulk
- Sanitary and kitchen joints
Doing it in-house
General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.
There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.
