Questions about Lasswade

Is Eldin Industrial Estate, near Lasswade, within your area?

Yes. Estates, retail parks and business parks around Lasswade, Eldin Industrial Estate among them, are all within reach. To start, just call the office on 01277 525 020 or send details through our quote form with the unit, the joints involved and your access times.

Would you work within a site like Midlothian Community Hospital?

Yes, hospitals are one of the sectors we cover. Each area is agreed with the ward or department and the estates team in advance.

Is Lasswade in your area?

Yes. We take on work across Lasswade, with one number for every area we cover.

How is access to upper-level joints handled?

That comes down to the access arranged for the job. Share what access exists or is planned when you send details, and we will plan the work with you.

Can you work in cold or wet weather?

Wet joints or temperatures outside the product’s range mean waiting. We plan for weather and keep you updated throughout the job.

Is old mastic on our building likely to contain asbestos?

It’s worth checking in any building from before 2000. The dutyholder holds the asbestos register, so ask for it before we start. Suspect material is left alone until it has been tested.

Is colour matching possible?

In many cases, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We confirm what’s available for the specified product when we quote.

Facade sealing in Lasswade, done properly

Facade sealants sit in the sun, rain and frost every day, and they wear out over time. How long a joint lasts depends on the movement it takes, its exposure, the product and how well it was installed. When it fails, the whole bead is cut away and the joint rebuilt. We work on window and door perimeters, stone and brick facade joints and perimeter joints where frames meet the structure, and the usual reasons a site gets in touch are water coming in around window frames and perimeter sealant that has split or peeled away. Facilities teams, main contractors and managing agents in Lasswade tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.

Outside mastic in Scotland needs a dry, frost-clear joint, and in a place like Lasswade that means watching the forecast. We build some give into the plan and agree it with the site manager.

We stand behind the joints we seal with a 12-month guarantee. That covers our preparation and application, and we come back if anything isn’t right.

Sites and facades in and around Lasswade

Lasswade has a number of hotels close by, all within 2 miles. Hotel schemes tend to have fixed reopening dates, so the mastic is programmed tightly with the other trades. Lasswade is in the east of Scotland, which is drier than the west. Frosty spells still affect external mastic dates. We programme around it with the site team.

For contractors refurbishing units at places like Eldin Industrial Estate (1.2 miles west of Lasswade), the mastic covers cladding panels, roller-door and window perimeters. For contractors at a school such as Lasswade High School Centre, sealing has to be finished before term starts.

Lasswade is about 1 mile north-west of Bonnyrigg, in Midlothian. We send applicators to Lasswade for facade joints, handled exactly as we handle every other area. We work across 34 places in Midlothian.

Anyone looking for facade sealing in EH19 and EH18 gets the same process as the rest of our area: details, then a fixed price, then sealing and a 12-month guarantee.

Nearby places we also cover include Bonnyrigg (1 mile south-east), Polton (1 mile south-west), Loanhead (2 miles west), Burdiehouse (2 miles north-west) and Rosewell (2 miles south) for facade joints. A short drive away, we cover Penicuik (5 miles south-west), Gorebridge (4 miles south-east), Mayfield (3 miles east), Shawfair (3 miles north), Roslin (3 miles south-west) and Easthouses (3 miles east).

Leave it or put it right?

Patch repairs over old sealant tend to come back. A full cut-out and fresh bead is the repair that holds, so you aren’t paying for the same joint twice. Around smaller places like Lasswade, halls, stores and seasonal buildings may not be checked often, giving water time to get in. Resealing early avoids that.

Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you’ll have a fixed figure to work with.

Commercial clients in Lasswade

Agents, factors and owners’ representatives all follow the same route: send the details, accept a fixed quote, and we carry out and guarantee the work. We can agree access arrangements and keyholder contacts beforehand.

Common problems we fix in Lasswade

Sometimes the substrate is the problem: crumbling render, spalling concrete or flaking paint take the sealant with them. We tell you when the edges need repairing before resealing.

It’s worth sending us details if you spot any of the following:

  • Discoloured or dirty facade joints
  • Failed sealant on precast panel joints
  • Cold air coming in at window perimeters
  • Hard, chalky sealant that no longer flexes

Hospital estates such as Midlothian Community Hospital (1 mile east of Lasswade) 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.

Questions to ask before you book

  • The named product and why it was chosen
  • How long is the guarantee, and what does it include?
  • Proof of insurance
  • Will failed sealant be removed rather than covered?

Choosing a commercial sealant contractor

Maintenance after handover

Regular inspection catches problems early. Specifically:

  • Note when each elevation was last resealed
  • Avoid patch repairs on failed facade joints
  • Plan facade sealing alongside redecoration
  • Brief window cleaners about newly sealed joints

Blocked sills and gutters push water at the joints. Good drainage keeps water moving off the facade instead of soaking the joints.

Use each reseal to correct the joint: the right width, backing rod and a sealant with enough movement capability. Repeating a faulty detail just repeats the failure.

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.

Coping and flashing joints

Where the specification calls for sealant at copings or flashings, we can seal them. They sit in the most exposed positions on the building.
