What we see in Leicestershire
What makes Retrofit Double Glazing work in Leicestershire is usually invisible once it is finished. Local stock is dominated by hosiery-era terraces, ironstone villages and large modern estates, which sets the sizes and profiles we work to. The weather does the rest: dry inland climate with sharp seasonal swings here, and movement cracking and bead shrinkage from repeated wet-dry cycling as the predictable result. In practice that means reworking the rebate so a sealed unit fits without bulking the section.
Nothing goes into manufacture until a surveyor has checked each opening on site. Ask us for a figure and you will get one, with the lead time stated alongside it.
Local factor worth flagging early: ironstone villages have distinctive mullion proportions worth matching.

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

Do you cover Leicestershire?
Yes. We cover the whole of Leicestershire including Leicester, Loughborough, Hinckley, Melton Mowbray and the surrounding villages. Ironstone villages have distinctive mullion proportions worth matching. Because dry inland climate with sharp seasonal swings, we allow for it at survey stage rather than discovering it on the day.
Will the finish need maintaining?
A factory-applied microporous finish typically needs inspection every three to five years, sooner on exposed coastal elevations. Maintaining it is far cheaper than letting a coating fail and the timber take up water.
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.
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.
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.
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.
