Sealant specialists in Cornhill
How long a joint lasts is decided before any sealant leaves the gun. Old silicone gives new sealant nothing to grip, so every trace of it is removed and the faces are cleaned until they’re sound and dry, with no dust or grease left. Where the sealant maker specifies a primer for that substrate, it goes on before the new bead. If you’re dealing with frame sealant that has cracked, shrunk or pulled away and sanitary sealant that has gone black and patchy, we can help, on floor and threshold joints, window and door perimeters and movement joints in walls and floors alike. Whoever orders the work in Cornhill, the brief is usually the same: a clear scope, tidy work and joints that don’t fail again.
In Cornhill, as anywhere, the first joints to go are usually the ones that work hardest: frame perimeters in the sun, floor joints at doorways and anything that gets wet every day.
Cornhill is part of one of Scotland’s big cities, where offices, shops, hotels and restaurants sit close together. Where a shop sits below tenement flats, work on the frontage or shared parts may involve the property factor.
Our 12-month guarantee is about workmanship, not wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we spell out the cover before we begin.

Commercial sealant contractors in Cornhill: the local picture
Cornhill lies within about 3 miles of the sea. Buildings near the sea put their external joints through more driven rain, with salt air nearer the beach. Sea-facing elevations are typically where failed joints show first. The 3 miles around Cornhill take in at least three named trading estates, business parks or retail parks. Sites like these see regular refits, with shopfronts, offices and staff areas to seal.
Refits at hotels like Northern Hotel (0.7 miles east of Cornhill) bring joints at vanity tops, bars and reception desks that guests see every day. Sites a few miles apart, such as Kittybrewster Shopping Centre and Berryden Retail Park, can share one programme and one point of contact.
Cornhill is about 1 mile north-west of Aberdeen, in Aberdeen. Cornhill sits inside our coverage and the rest of Aberdeen, with the same fixed quotes and 12-month guarantee as everywhere else. Our Aberdeen coverage takes in 40 places, from busy centres to rural villages.
Business premises anywhere in AB16, AB25 and AB24 are within our area. If your site is on Rowan Road, Morgan Road and Cairncry Road or close by, we can quote for sealant joints.

When to call us in Cornhill
The wrong sealant in the wrong place is a common cause of early failure. Decorators’ caulk on a joint that moves, acetoxy silicone on stone or metal, or a stiff sealant on a facade all let go sooner than they should. BS 6213 gives guidance on choosing construction sealants.
Typical triggers for a call:
- Shrunken sealant along kitchen worktops and splashbacks
- A top-up bead over failed sealant, now lifting
- Movement joints packed with grit and debris
- Damp patches where an external joint has failed
Units at retail parks like Kittybrewster Shopping Centre (0.7 miles east of Cornhill) change hands and get refitted, with new joints at every frontage.
Questions to ask before you book
- Health and safety accreditation such as CHAS
- Whether primer will be used where the manufacturer specifies it
- Their approach to joint depth and backing
- Their public liability cover
Doing it in-house
For a quick touch-up, site staff may be fine, 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. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
Looking after the joints
Keep the joints in good shape with a few simple steps:
- Ask cleaners to use a soft cloth and mild cleaner on sealant
- Log reseals in the O&M or maintenance records
- Check joints after other trades have worked nearby
- Have extract fans checked so wet areas dry out
Keep an eye out for other trades after we’ve gone. When fittings are moved or cabling added, the sealant nearby is easily disturbed and the joint gets left open. If that happens, speak to us on 01277 525 020 or send photos by email and we’ll price putting it right.
A failed external joint lets water in every time it rains. It can run into cavities, insulation and internal finishes long before anyone sees a stain. Resealing early keeps the problem in the sealant and out of the building.
Diagnose, treat, sign off
When we get to site, we sign in, go through any site induction and check how permits are handled. Floors, finishes and fittings next to the joints are covered before any cutting starts, and the work usually takes a few hours to several days on most single sites, depending on joint lengths and access. City jobs in Cornhill normally need parking and loading planned. Tenement closes, shared stairs and factor approvals may also be involved.
- First, details come to us: photographs, drawings or a schedule of the areas.
- Next comes a diagnosis and a fixed quote.
- We plan around your site hours and access windows, phasing the work where areas have to stay in use.
- We strip the failed bead and prepare both faces of the joint.
- Backing and primer go in where needed, then the chosen sealant is applied and tooled.
- Each area is inspected, signed off and backed by our 12-month guarantee.
Before we start on site
- Move anything stored against the joints
- Warn occupants and staff about the work
- Share your working hours and any access restrictions

What affects the price in Cornhill
The price varies from site to site. It mainly depends on:
- Working within restricted access windows
- Access and working height
- Which sealant the job calls for
- How much existing material needs removing
There’s no price list, since every building and every scope is different. Call for a quote.
What to include in your enquiry
However big the job, these details speed things up:
- The asbestos register, for older buildings
- Drawings or a marked-up plan, if available
- Any dates the work must fit around
- Photos of the joints, close up and from further back
Every job follows the same four steps: send details, get a quote, we seal, guaranteed. To take the first step, speak to us on 01277 525 020 or email a schedule or drawings.
What happens if it’s left?
Spot repairs have their place. If the rest of the bead is the same age and product, though, it’s usually close behind. Where it helps, we quote a patch and a full reseal side by side. In a tenement or shared city building, water from a failed joint can reach other owners’ property, which makes early repair simpler for everyone. Acting early avoids disputes and bigger repairs.
A quote for sealant joints depends on quantities, condition and access, plus any specification you are working to. Call for a quote.

Common questions from Cornhill clients
Our building in Cornhill is near the coast: does that change the sealant?
It can. Wind-driven rain and, closer to the shore, salt air are harder on external joints. Product choice and preparation matter more, and sea-facing elevations are worth inspecting more often.
Can you work at a site such as Kittybrewster Shopping Centre, by Cornhill?
Yes. Our area takes in Cornhill and its surroundings, with estates and business parks such as Kittybrewster Shopping Centre included. To start, just call the office on 01277 525 020 or email the details over with the unit, the joints involved and your access times.
Can you supply RAMS and insurance details?
Send your site requirements with the enquiry, and we’ll confirm the RAMS, insurance and CSCS details with the quote. From you, we will need the asbestos information for older buildings and any site rules.
Do you hold CHAS accreditation?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member.
Which sealant will you use?
The specification comes first, if there is one. Without one, the joint decides: its movement, its surfaces and what it has to cope with.
How long will the new sealant last?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Sealant joints are maintenance items, so inspect them regularly.
Is your work guaranteed?
It’s backed by our 12-month guarantee. Should a joint we sealed give trouble during those 12 months, let us know and we will look at it.
