How we handle facade sealing in Steinis
External sealing depends on the weather more than most trades. Joints have to be dry and the air and surface temperature within the product’s range, so frosty or damp mornings can hold work back. We plan for that and keep you updated. If you have patch repairs that keep failing and discoloured or dirty facade joints, we can help, whatever the surface. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Steinis is the same: the right product in a properly prepared joint.
For a site around Steinis, 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.
Every job ends the same way: guaranteed. Our workmanship is backed for 12 months, and we explain exactly what that covers when we quote.

Why deal with it now?
Failed joints let in more than water: occupants notice draughts and cold spots around windows. Resealing deals with the draught as well as the leak. Buildings that aren’t in daily use, such as halls and seasonal premises, may let water in unnoticed, giving water time to get in. Resealing early avoids that.
Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.
What you get with us
- Fully insured, including public liability cover
- Specification-led, product-correct work

Before you send an enquiry
Good information means a firmer quote. When you get in touch, include:

- The product your specification calls for
- The site address and postcode
The quickest route to a quote is a few photographs and the site postcode. Send them through the quote form, or phone 01277 525 020 or email a schedule or drawings if you’d rather talk the job through.
Sites and facades in and around Steinis
Steinis lies within about 1 mile of the sea. Facades and window perimeters on coastal schemes take more wind-driven rain, and salt air nearer the shore, so joint design, primers and product choice deserve extra care. Scotland has its own building regulations, and in Steinis warrants come from the local authority verifier. The mastic follows the specification that goes with the warrant.
Extensions at sites like Western Isles Hospital (1.3 miles west of Steinis) usually sit beside working departments, and the mastic follows strict access rules. Units on estates such as Parkend Industrial Estate, 1.2 miles to the south of Steinis, tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal.

FAQs: Steinis
Will you travel to Steinis on the island?
Yes, Steinis is within the area we cover. Every Scottish council area is within our area. We group island work where we can and plan around the crossings.
Does the sea air around Steinis change the choice of sealant?
It can, yes: buildings near the sea take more wind-driven rain, and salt in the air nearer the shore. Product choice and preparation matter more, and sea-facing elevations are worth inspecting more often.
How long before the joints can be used?
Curing time varies by product, and we confirm it on the day, and flag anything to keep off until it has cured.
Is colour matching possible?
Often, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We confirm what’s available for the specified product when we quote.
Are you CHAS accredited?
Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.
Do you replace windows or glass?
No. That work needs a glazing specialist. What we seal are the joints around frames and panels on commercial buildings.
Can you work on upper floors?
That varies with the building and the access on offer. When you call the office on 01277 525 020 or email the details over, describe the access, and we will agree the approach together.

How the job changes by surface
Window and door perimeters
Aluminium, PVC-U and timber frames each have their own preparation needs. We clean and prime to the sealant maker’s guidance for each surface.
Brick and stone facades
Brick and stone facades have perimeter and movement joints that need a compatible sealant. We avoid acetoxy silicone, which can stain some natural stone, with primer where its maker specifies.
For managing agents and facilities managers
When you manage a building on behalf of an owner, you need clear quotes and clear reporting. You get a fixed quote, an agreed scope and a walk round at the end.
Hospitality, education, healthcare, office and retail clients come to us directly as well. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.
From enquiry to sign-off
Before we leave any area, the masking comes off, the area is cleaned and every joint is checked with your site contact. If an area should be left alone while the sealant cures, we say how long and put signs out. Where we can, we combine work around Steinis with other jobs nearby, to make the most of each trip. Tell us how flexible your dates are.
- Photos, drawings or a visit tell us about the joints and the access.
- We confirm the joint type, movement and the specified product.
- The existing bead comes out in full.
- Primer is applied where the maker specifies it.
- Rod goes in to fix the depth, then the joint is sealed and tooled.
- We go over the completed work with you before leaving.
