Commercial sealant contractors in Dennistoun, done properly
Mastic Doctor has been sealing joints for businesses and contractors since 2005: we’re CHAS accredited and a Constructionline member, our applicators hold CSCS cards, and we carry five million pounds of public liability insurance. If your site needs RAMS, an insurance certificate or CSCS details, say so and we will confirm with the quote. We work on movement joints in walls and floors, external facade joints and kitchen worktops and splashbacks, and the failures we are asked to look at most are shrunken sealant along kitchen worktops and splashbacks and weathered facade sealant that no longer flexes. For commercial sealant work in Dennistoun, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.
We price commercial jobs in Dennistoun from photos, drawings or a site visit, with the scope listed so everyone knows what’s included.
In Scotland’s cities, commercial premises are packed closely, from stone-fronted offices to shops on the ground floor of tenement blocks. Shop units under tenements can bring the property factor into the picture when the work touches shared parts.
Work we carry out in Glasgow comes with a 12-month guarantee. Should something we installed fail, call 01277 525 020 or email us and we’ll come back to it.

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.
For main contractors, we work as the sealant subcontractor, on new build and refurbishment alike. We work to your programme, your specification and your site rules, with CSCS-carded applicators on site.
Common questions from Dennistoun clients
Can you match sealant colours for premises in Dennistoun?
Yes, sealants come in a wide range of standard colours, and matching to RAL references, cladding, stone or frames is a common request. Send colour references or photographs and we will confirm what’s available for the product.
Must a hotel around Dennistoun close while you work?
In the majority of cases no closure is needed: we work room by room or floor by floor. Housekeeping and our team agree each day’s rooms.
Do you hold CHAS accreditation?
Yes. We’re CHAS accredited and a Constructionline member, which helps with supplier vetting.
How long does a job like this take?
We plan the time on site around your programme and access. You’ll have an expected duration with the quote.
What about asbestos in old mastic?
We check the asbestos register or survey before any old sealant is disturbed. Managing asbestos is the dutyholder’s responsibility and removing it isn’t something we do.
Do you work for facilities managers and managing agents?
Yes. Use our quote form to send the site details, or phone or email us.
How do we get a quote?
Price depends on joint lengths and widths, how much removal is involved, the product, access and phasing. For a fixed quote, send details through our quote form.

What the job involves on each surface
Window and door perimeters
Where frames meet the surrounding wall, sealant is the weather line. We remove the old seal, prepare the faces, fit backing where needed and seal again with a product chosen for both the frame and the wall.
Washrooms and toilets
Around WCs, urinals, vanity tops, IPS panels and cubicles, sealant is wet most of the day. Old sealant comes out and a sanitary silicone with anti-mould additives goes in, phasing the rooms so not every toilet is closed at once.
Frontages, fit-outs and joints in Dennistoun
Dennistoun has at least three named business or industrial parks inside a 3-mile radius. Units on sites like these change tenants and get refitted, and each refit leaves joints to seal. The area within 2 miles of Dennistoun holds a good number of hotels. Refits in hotels bring joints at vanity tops, bar counters and reception desks where the colour has to suit the scheme; work is planned so the hotel keeps trading.
A hotel such as Bellgrove Hotel (0.5 miles south-west of Dennistoun) shows how much sealant a hospitality building has on show, from bathroom joints to the bar. A business with units at Glenpark Street Industrial Estate and City Park Industrial Estate needn’t use two contractors for its sealant. Premises within reach of Duke Street station, less than half a mile south-east of Dennistoun, often have busy frontages where joints are seen by everyone passing.

What sets the cost
We price every job individually. The main factors are:
- Working within restricted access windows
- Removal of failed or old sealant
- Access and working height
- Location, for remote and island sites
The product called for affects the cost, as does the preparation each joint needs, such as cutting out, priming or new backing rod. Access, phasing and site rules also count.
Sending details for a quote
Diagnosis starts before we arrive. Tell us:
- Rough lengths or quantities, or drawings if you have them
- Anything awkward about access or site hours
- Where the site is, with the postcode
- A wide shot and a close-up of the area
Photos, drawings or a schedule of the joints are often enough for a fixed quote. Where a site visit makes more sense, we’ll arrange one.
Our process
Tell us your site hours and access windows and we will plan around them. While we are working, the area stays contained and tidy, and your contact hears from us before we move to the next area. City jobs in Dennistoun typically need parking and loading planned. Shared closes, stairs and the property factor may need to be part of the plan.
- First, details come to us: photos, drawings or a schedule of the areas.
- The failure is diagnosed and a fixed quote issued for the work agreed.
- Site hours, access windows and the order of areas are agreed before we start.
- The failed bead is removed and the joint faces cleaned until they’re sound and dry.
- Backing and primer go in where needed, then the chosen sealant is applied and tooled.
- We walk the completed areas with you and sign them off under the 12-month guarantee.
Before we start on site
- Move anything stored against the joints
- Agree which areas must stay open
- Explain the parking and delivery arrangements
Getting a fixed quote
Send details, get a quote, we seal, guaranteed: that’s how every job runs. The first step is to phone 01277 525 020 or use the quote form with what you know.
Advice
What happens if it’s left?
Patching the worst lengths can be the right call on a tight budget. Where the remaining sealant is just as old, it tends to fail soon after. 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. Acting early avoids disputes and bigger repairs.
There’s no price list, because the scope varies so much from one building to the next. Call for a quote and we’ll price your job on its own details.

Read our cost guide or how we’re accredited.
Looking after the joints
Once the work is signed off, these steps help:
- On pre-2000 buildings, share the asbestos information before work starts
- Put external and wet-area joints on a regular inspection round
- Log reseals in the O&M or maintenance records
- Check joints after other trades have worked nearby
We stand behind the workmanship with a 12-month guarantee. Keep the handover details with your O&M or maintenance records.
Tenants and staff spot black or split sealant quickly, and in a hotel, office or shop it makes the whole space look neglected. Replacing it on a planned cycle keeps complaints down.
