Double-glazing and the accompanying locking systems enhance home security, ensuring the safety of your Motherwell home. Double-glazed windows, unlike standard single-glazing, provide increased resistance to break-ins.

Our windows have steel-reinforced frames as a standard feature, which makes it very difficult for forced entry. Additionally, we provide Yale multi-point locking systems for both our windows and doors to further enhance security.

Reduced Condensation

Reducing noise with double glazing

Condensation is a common issue for homes that have single glazing or double-glazed units that are not functioning properly. The growth of mould and presence of damp patches can have an impact on health and contribute to respiratory illnesses. Additionally, over time, condensation can cause damage to the structure of your home.

Replacing your existing windows with new double-glazing can significantly reduce condensation, sometimes by up to 85%.

Double-Glazing Motherwell - FAQs

Most frequent questions and answers

In most cases, installing double-glazed windows or doors does not require planning permission. However, if you are installing them in a listed building or in a conservation area, you will typically need to obtain listed-building consent or planning permission.

If you are considering double-glazing as a home improvement investment, we can provide guidance on potential planning permission concerns for your property in Motherwell.

The lifespan of double-glazing is influenced by factors such as the quality of installation and materials, as well as window maintenance.

Our products are designed to be of high quality and have a lifespan of at least 20 years. UPVC windows and doors, for instance, may last even longer if they are in a protected area and not excessively exposed to severe weather conditions. Certain types of double-glazing can potentially last up to 50 years.

Regular cleaning and maintenance can help prolong the lifespan of your double-glazed units. It is recommended to clean the glass, frames, and sills using a soft cloth or sponge and a mild detergent to effectively remove dirt without causing any scratches on the surfaces. Avoid using a high-pressure hose to clean your window exteriors as this can potentially damage the seals and result in leakage.

Window maintenance also involves regularly inspecting the locks and seals for any issues and promptly addressing any necessary repairs.

Whether a double-glazed window needs to be replaced or repaired depends on the cause of the problem. If the sealed unit has been compromised, a full window replacement is typically necessary. If the problem is less severe, such as minor cracks in the frame or damaged hardware, these issues can typically be fixed.

The price of double-glazing can vary depending on factors such as the size of the window or door, the quality of materials, the level of customisation, and any necessary structural work. Generally, new installation composite doors and windows tend to be more expensive compared to UPVC windows and doors.
