Timber glazing upgrades in Derby
We take a fair volume of Retrofit Double Glazing work across Derby, and almost none of it repeats. Local property is overwhelmingly Peak District gritstone cottages, mill housing and Georgian spa stock, which is why we never quote from a catalogue. upland cold with heavy snow loading and hard frost sets the pace of decay, and frost heave damage and swelling on unbalanced-finish joinery is how it shows up first. In practice that means reworking the rebate so a sealed unit fits without bulking the section.
The site visit comes first, because assumptions made in an office get paid for on site. One call is usually enough for us to tell you roughly where the price will land.
Something particular to this area: Peak Park properties face some of the tightest external alteration controls in England.

“The survey showed most of the loss was around the frames, not through the glass at all.”
Verified client, Derbyshire“Half the cost of replacement and the rooms hold heat noticeably better.”
Verified client, Derbyshire“They fitted trickle vents we had not thought about, which stopped the condensation.”
Verified client, DerbyshireDerby questions
Do you fit, or supply only?
Both. Supply-only is common for trade and contractor clients. For private clients we usually recommend supply and fit, because responsibility for the fit and the finish then sits in one place.
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 price from drawings?
Yes. Send a drawing set or a schedule and we will price against it. If anything is ambiguous we will query it before quoting rather than assume and reprice later.
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.
What guarantee do you provide?
Ten years on workmanship, covering manufacture and the factory-applied finish. Where we install, the installation is covered too. It is issued in writing with the handover paperwork.
