Windows are an essential element of your home, contributing to its aesthetics, insulation, and overall value. Like anything else in your home, they do have a finite lifespan.

How to Identify When Your Windows Require Replacement

There are numerous telltale signs that your windows need replacement. These signs may include drafts, difficulty in opening or closing, condensation between glass panes, excessive noise seepage, and visible structural damage such as warping or rotting. If you notice any of these signs, it’s an indicator that your window has surpassed its prime and needs to be replaced.

Determining When to Replace Your House Windows

There’s no definitive answer as to when exactly you should replace your windows as it varies depending on factors such as age, condition, and type of windows. Generally, windows that are over 20 years old are prime candidates for replacement. However, this doesn’t necessarily mean that all 20-year-old windows need to be replaced. At Southworth, we encourage homeowners to consider the type and condition of their windows alongside their age.

Recognising When Your uPVC Windows Need Replacement

Unplasticized Polyvinyl Chloride (uPVC) windows are favoured for their durability and energy efficiency. However, they’re not invincible.

Identifying a Problem Window

A window might not show visible signs of damage but can still be causing issues. These can include drafts even when closed, water leakage during rainfall, or damaged or rotten frames. If a window consistently presents these problems, it’s time to replace it. Southworth’s experienced team can help identify such issues and advise on the best course of action.

Expected Lifespan of uPVC Windows

On average, uPVC windows last between 20 to 25 years. Factors such as exposure to harsh weather conditions, maintenance practices, and installation quality can impact their lifespan. Regular inspections and prompt repairs, services which Southworth provides, can help extend their life.
