Timber glazing upgrades in Greenock
If Thermal Survey in Greenock were straightforward, there would be a stock size for it. With sandstone tenements, Georgian New Town terraces and post-war housing schemes making up much of the area, off-the-shelf sizes rarely line up. The weather does the rest: cold wet winters with strong westerly exposure here, and sash and case failure in tenement stock and cill decay at stone junctions as the predictable result. In practice that means measuring where heat is going before anyone recommends a spend.
Manufacture only starts once the survey figures are agreed with you in writing. One call is usually enough for us to tell you roughly where the price will land.
Something particular to this area: Scottish sash and case construction differs from English box sash and needs matching.

“The survey showed most of the loss was around the frames, not through the glass at all.”

How long does a typical order take?
Most made-to-size orders run six to ten weeks from survey to delivery. Conservation and heavily detailed work can take longer, and we confirm the lead time in writing at quotation rather than leaving it open.
Can you work on a listed building?
Yes, and a significant share of our work is listed or conservation area. We can supply drawings and section details to support a listed building consent or planning application, though the consent itself remains the owner's responsibility.
Do you work in hardwood or softwood?
Both. Engineered hardwood is the default where movement or exposure is a concern, and slow-grown softwood is often the better value choice for painted work in sheltered positions. We will tell you which we would specify and why.
How do you handle glazing?
Standard double glazed units for most work, and slim-cavity units where a conservation officer has restricted sightlines. Single glazing with putty lines is available where the consent requires it.
Can you match an existing profile?
Yes. If you can supply a section, a photograph with a rule in shot, or an old unit, we can replicate the profile. For conservation work this is usually the condition the planning officer will apply.
