How we handle facade sealing in Howwood
External joints face UV, rain, temperature swings and building movement all year, so they don’t last indefinitely. Life depends on movement, weathering, product choice and the quality of the original work. When it fails, the whole bead is cut away and the joint rebuilt. We work on stone and brick facade joints, window and door perimeters and coping and flashing joints, and what we’re called in for most is patch repairs that keep failing and damp patches beside frames after rain. One point of contact handles commercial sealant work in Howwood from the first photos to the final walk-round, for single jobs and planned programmes alike.
In smaller places such as Howwood, building work tends to be single schemes rather than big developments. Exposed elevations in Scotland put facade and perimeter joints to work from day one, so the sealant choice matters.
Work we carry out in Renfrewshire comes with a 12-month guarantee. Should something we installed fail, give us a call on 01277 525 020 or email the details over and we’ll come back to it.

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.
Cladding panel joints
On sealed panel systems, every joint keeps water out. Failed runs are cut out and rebuilt end to end.
Signs you need facade sealing in Howwood
The wrong product causes its share of trouble: an acetoxy cure can mark stone or corrode some metals, and interior products break down outdoors. Most external joints call for a neutral-cure, facade-grade sealant.
Any of the following is a good reason to get the joints checked over:
- Perimeter sealant that has split or peeled away
- Perimeter joints where frames meet the structure
- Unsightly perimeter sealant on a visible elevation
- Gaps between rainscreen or cladding panels
Hospital estates such as Merchiston Hospital (to the north-east of Howwood) tend to grow and change in phases, often next to occupied wards, so facade and perimeter sealing has to fit the estates team’s plan.
What your quote should include
- The named product and why it was chosen
- Their plan for phasing and protecting the area
- Will failed sealant be removed rather than covered?
- Proof of insurance
What sets the cost
Sealant work doesn’t have a standard rate, since sites vary so much. What we look at:
- Any access equipment needed
- Specialist products, such as fire-rated or hygienic sealants
- Backing rod, priming and other preparation
- Working within restricted access windows
We don’t publish prices, because the scope varies so much from one building to the next. For a fixed figure, call for a quote and we’ll price your job on its own details.
Details that help us quote
To price the job accurately, we need to understand the site. Send us:
- Access details, including height
- The site address and postcode
- Clear photos of the problem areas
- Asbestos survey details if the building is older
Quotes are fixed against the scope you send, so the cost is agreed before work starts. To start the process, phone 01277 525 020 or send photos by email.
Our process
Inspect, seal, sign off: that’s the shape of every visit. First comes an inspection and agreement on scope, then the work is carried out to the specified product and detail, and the job ends with a walk round and sign-off. For work around Howwood, we aim for one trip, so photos, sizes and a full list matter. Outside work also needs a suitable weather window.
- We look at the joints, the drawings and the access before pricing.
- Failed sealant is cut out along its full length.
- Both faces are cleaned and, where the product needs it, primed.
- Closed-cell rod fixes the depth, and the sealant grips two sides only.
- The new sealant goes in and is tooled firmly onto both faces.
- We walk the finished joints with you before handing over.
What we need from you
- For older buildings, check the asbestos register before work
- Let building users know which areas are affected
- Clear stock, furniture or equipment away from the joints

Questions we are asked in Howwood
Is Howwood off your patch?
Not at all. Howwood is within our area. Our area covers all of Scotland, cities, towns and islands alike. We plan jobs in smaller places so return trips are kept to a minimum.
Can the mastic package for our job in Howwood follow the site programme?
Yes. Send the programme and drawings, and we’ll plan the mastic to suit the stages. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.
Are you CHAS accredited and on Constructionline?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member.
Are you fully insured?
Yes. We’re fully insured, including public liability cover.
Do you seal on top of existing sealant?
No, never. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.
Can you work in cold or wet weather?
Wet joints or temperatures outside the product’s range mean waiting. The programme allows for it and we tell you if the forecast changes things.
Do you use silicone for external joints?
Most facade and window perimeter joints take a low-modulus neutral-cure silicone. Some joints call for hybrid, PU or polysulphide instead.
Maintenance after handover
Regular inspection catches problems early. Specifically:
- Add perimeter sealant to planned maintenance checks
- Check the asbestos register before old mastic is disturbed
- Report water ingress at frames as soon as it shows
- Never let anyone seal over old sealant
Keep a note of which product went in and when. Future work can then match the product and colour across the elevation.
In pre-2000 buildings, check the asbestos register before old sealant is cut out. Older sealants can contain asbestos.
Mastic packages on Howwood sites
In Howwood, as across Scotland, building warrants are issued by the local authority verifier under the Scottish regulations. The mastic package follows the approved specification.

Hotel extensions and refits, at places such as Bowfield Hotel & Country Club, 0.9 miles south-west of Howwood, normally run between busy periods, so the sealing is squeezed into short windows.
