Construction mastic in Geirinis, done properly
A typical mastic package covers more than window perimeters: frame perimeters inside and out, caulking to trims and boards where the specification calls for it, sanitary silicone, kitchens, and the final snag list. One contractor for all of it keeps the responsibility in one place. The enquiries we see most involve failed sealant in an existing building being refurbished and early adhesion failures on new external joints, across brick and block movement joints, cladding and panel joints and internal decorators’ caulk. Whoever orders the work in Geirinis, the brief is usually the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
In smaller places such as Geirinis, building work tends to be single schemes rather than big developments. The mastic still needs to suit exposed elevations and Scottish weather.
Building owners and contractors get the same cover: twelve months on the work we carried out. It doesn’t extend to damage, faults in the building or work by others, and we are upfront about that.

Sites and facades in and around Geirinis
With the shore within about 1 mile, Geirinis counts as a coastal location. On a coastal site, facade and perimeter joints face driven rain and, closer to the beach, salt, so joint design, primers and product choice deserve extra care. Geirinis is on Scotland’s wetter western side. External mastic needs dry spells, with internal work ready to fill the wet days.
For contractors building in or near Geirinis, we seal to the drawings, the specification and the programme.

Why deal with it now?
A quick bead over a damaged joint can get an area past inspection, but it won’t last. New sealant laid on old or dirty sealant has nothing to bond to and the defect reappears in the defects period. We cut out and redo the joint properly. In Scotland, wind-driven rain finds a failed joint quickly, so it’s worth renewing joints around Geirinis before they leak.
Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a fixed quote and we will explain how it’s made up.

Should maintenance staff do it?
Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong usually costs more in the end than doing them right.
There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we’ll confirm the paperwork you need with the quote.
Common problems we fix in Geirinis
Shrinkage and settlement in the first months put new joints under strain. Materials lose construction moisture and shrink, which opens up internal joints, particularly where caulk has been used in a joint that moves. Choosing the right product for each joint reduces that.
These are often picked up first by site or facilities staff:
- Perimeter gaps outside the sealant’s range
- External joints sealed in damp or cold conditions that are now failing
- Window and door perimeters that won’t pass inspection
- Snag items on joints that need redoing before handover
Window perimeters and facade joints around Geirinis need correct width, depth and backing rod as much as a neat finish.
Before you book anyone
- Whether primer will be used where the manufacturer specifies it
- Proof of insurance
- What the guarantee covers, and for how long
- Are they CHAS accredited or on Constructionline?
When something else is needed
Being straight saves everyone time. Fresh joints won’t solve:
- Damage to finishes by other trades after we have sealed
- Designing joint widths or choosing the specification (that sits with the designer)
- Glazing units that are cracked or misted
If you are not sure, just ring 01277 525 020 or send photos by email and we’ll give you a straight answer.

Your questions answered
Will you travel to Geirinis on the island?
Yes. Every Scottish council area is within our area, and that includes island locations such as Geirinis. Island work is planned around ferry crossings and the weather, so photographs and a full list before we travel are essential.
Does a coastal location like Geirinis affect which sealant is used?
It can, yes: buildings near the sea take more wind-driven rain, and salt in the air nearer the shore. That puts more weight on product choice, primers where the manufacturer specifies them, and correct joint sizing.
How many days will you need on site?
It depends on the scope, though a typical visit typically takes as long as the agreed sequence needs, which comes down to joint lengths, access and handover dates. For bigger or phased jobs, we will set out a timescale with the quote.
Will you come and look before quoting?
Photos, drawings or a schedule are often enough to quote. Where they aren’t, we arrange a site visit.
What does a mastic package normally include?
Window and door perimeters, internal decorators’ caulk where specified, sanitary joints, kitchens, movement joints and snagging. The scope follows your specification.
When is resealing likely to be due?
It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.
Can you send site paperwork?
Requirements differ from site to site, so list what you need, whether RAMS, insurance or CSCS details, and we’ll confirm with the quote.
Surface by surface
Snagging before handover
Damaged, missed or untidy joints make up most snag lists. Snagging can be included or priced separately.
External facade and movement joints
Movement joints in the facade are sealed with a product suited to the expected movement. Depth is controlled with backing rod so the bead bonds to two sides only.
