Timber glazing upgrades in Porthmadog
Retrofit Double Glazing across Porthmadog tends to be driven by the condition of what is already there. Local property is overwhelmingly slate-quarry terraces, Victorian resort stock and stone farmhouses, which is why we never quote from a catalogue. severe Irish Sea exposure with very high rainfall is the local complication, and salt and rain combining to strip finishes and open glazing joints is what it eventually causes. Where we put the effort is reworking the rebate so a sealed unit fits without bulking the section.
Nothing is ordered until someone has stood in front of the opening with a tape. We will price it properly in writing, and we will tell you if it is not worth doing.
Local factor worth flagging early: Llandudno's Victorian frontages are protected as a coherent conservation set.

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

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.
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.
Do you deliver nationwide?
Yes, we deliver across England, Wales and Scotland. Delivery is priced into the quotation so there is no separate charge added later.
Do you take a deposit?
Not before the measured survey. A deposit is only requested once the survey is complete and you have approved the final schedule and price.
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.
