Here you will find no invented prices and no promised percentages: you will find what pushes a quote up or down, how to read it line by line, and how the tax-deduction process actually works.
On seven main factors: material, sizes and number of sashes, type of glass, hardware and special openings, finishes and colours, difficulty of fitting and extra work (shutter boxes, sills, disposal). That is why a "price per square metre" found online says very little about your home.
A serious quote is itemised line by line: product and material for each window, type of glass and Uw value, hardware, fitting, finishes, extra items and what is excluded. If a quote is a single line with a total, you cannot compare it with any other.
In Italy, replacing windows and doors can fall, under certain conditions, within the deductions for energy saving (the "Ecobonus" area) or for renovation ("Bonus Casa"): the expense is recovered through your tax return over several years, paying by speaking bank transfer (bonifico parlante) and sending the file to ENEA within the required deadlines.
The typical conditions to check are: the new frames must meet transmittance (Uw) limits for the climate zone — Pontoglio is in zone E — it must be a replacement of existing frames, and the documents (invoices, data sheets, ENEA receipt) must be kept. Percentages, caps and deadlines change with budget laws.
Note dated 10 November 2026: we do not publish deduction percentages as if they were certain, because rates and caps are updated by law. At quote time we check together the ENEA and Revenue Agency rules in force and tell you which route applies to your job. This page is a general explanation, not tax advice.
Usually three things: large glazed areas (French doors and wide sliding doors), special glass (triple, acoustic or safety glass) and the work around the opening — shutter boxes to replace, out-of-square openings, complete finishes. The material matters, but often less than people think: that is why a survey with real measurements beats any "per square metre" estimate.
In general, replacing windows and doors with others of the same characteristics falls under free building work (edilizia libera), so no specific permits. Exceptions exist: listed buildings, historic centres with rules on materials and colours, changes to sizes or façades. This is general information, not legal advice: for your specific case we check the town's rules before starting.
Typically: invoices and speaking transfers, data sheets of the frames with transmittance values, and details of the property and owner. The ENEA submission must be sent within the deadline from the end of the work (generally 90 days). At quote time we list the exact documents under the rules in force and who handles the submission — an item to confirm in the quote.
If you have a quote in front of you and it says little, ask us to explain the lines: no obligation.
