Double Glazed Windows

Prices vary depending on window size, style, glazing choice, hardware, and the number of openings. Access and any extra work (like making good reveals) can also affect cost. MPN provides a clear, written quotation after a survey, with the specification set out so you can compare like-for-like.

Most window installations are completed within one to two days, depending on how many windows you’re replacing and the complexity of the job. We’ll confirm a realistic schedule in advance and keep disruption to a minimum. MPN fitters protect floors and tidy as they go, then finish cleanly.

Double glazing can help reduce condensation, especially when upgrading from older single glazing or failed units. However, condensation is also linked to humidity, ventilation and lifestyle. MPN can recommend glazing and trickle ventilation options, plus simple changes to help manage moisture and keep rooms feeling fresher.

Yes – modern double glazing is designed to retain heat, reduce draughts and improve comfort. Your exact efficiency depends on the frame system and the glass specification you choose. MPN will advise on options that best suit your home, helping you balance performance, budget and appearance.

Security is built into the design, with strong frames, quality hardware and multi-point locking on most opening styles. You can also choose upgraded cylinders, laminated glass, and additional security features where needed. MPN will recommend the right security level based on your home and location.

Replacement windows and doors must comply with Building Regulations. As a FENSA registered installer, MPN can self-certify compliant installations and provide the correct certification for your records. This helps when selling your home, and gives added reassurance that the work meets recognised standards.

MPN provides long-term protection for your installation, including a 20 year guarantee on supplied and fitted products (subject to terms). You’ll receive the details in writing, along with guidance on how to care for frames, locks and seals. If you ever need support, our aftercare team is available.
