Where to start with replacing windows

Last updated: July 2024 | 3 min read

Windows not only help with energy efficiency and security, but also lend an aesthetic appeal to your house. Older windows often become less effective over time. Recognising when to replace windows can save you money on energy bills and improve your living environment.

Add value to your home, by keeping a close eye on areas that can be improved, including replacing windows. Read on to learn more.

Is it time to replace your windows?

Look for these indicators: difficulty opening or closing, noticeable drafts, condensation between panes, and decaying frames.

In older properties, single-glazed windows often contribute to increased heating bills. Upgrading to double-glazing or energy-efficient windows can reduce these costs.

Benefits of replacing outdated or damaged windows

Installing new windows offers several advantages beyond mere aesthetics. Energy efficiency is a primary benefit. Modern windows provide better insulation, keeping your home warm in winter and cooler in summer, thus reducing heating and cooling costs.

Learn how to make your house more energy-efficient.

Improved security is another advantage, as newer models often come with advanced locking mechanisms.

Noise pollution reduction is particularly noticeable in urban areas or homes near busy roads. Replacing windows can increase your property's value, making it a worthwhile investment.

How energy efficiency impacts your decision

Energy efficiency is a big incentive to replace windows. Older windows, especially single-glazed ones, are often poor insulators. This leads to higher energy bills due to more heating in the winter and more cooling in the summer.

Energy-efficient windows, like double or triple-glazed units, improve insulation. This not only reduces energy bills but also enhances comfort by maintaining a consistent indoor temperature.

When choosing replacement windows, consider their energy rating. Windows with a higher rating offer better insulation, contributing to a more comfortable and cost-effective home environment.

Costs of window replacement

Breaking down the price of replacement windows

Replacing windows requires a substantial investment. The cost varies depending on factors like frame material, window style, and the specific needs of your property.

High quality windows, while initially more expensive, can save money in the long run due to improved energy efficiency.

You must compare prices from different suppliers and consider the long-term benefits versus the initial expenditure.

What factors affects the cost?

When you replace windows, several elements influence the total cost. The size and style of the window, materials used in the window frame and glazing, and whether your property is in a conservation area or a standard residential area, all play a role.

In period properties, for example, replacing old windows with wooden windows that match the original style may be more expensive but necessary for maintaining the property's character.

How to budget for window replacement

Budgeting for window replacement requires a careful balance between cost and quality. Start by getting quotes from several window installers to gauge the market rate. Remember, the cheapest option isn't always the best.

Factor in the resulting energy savings from double-glazing or highly durable materials. Consider the project as an investment in your home's comfort and value.

Cost-effective solutions for window replacement

Finding cost-effective solutions doesn't mean compromising on quality. Look for competitive prices but also focus on the value you're getting.

Double-glazed windows, for instance, might have a higher upfront cost but can improve energy efficiency, leading to lower energy bills.

Sometimes, replacing all the windows in your house at once can be more economical than doing it piecemeal.

Choosing the right type of windows for your home

Different styles of windows: pros and cons

Replacing windows in your home is not just about utility. It shapes your living space's aesthetics and functionality. When you consider different styles of windows, think about both their visual appeal and their practicality.

Casement windows, for example, are known for their unobstructed views and excellent ventilation. On the other hand, sash windows, particularly popular in older UK homes, offer a classic look but might be more challenging to clean.

Bay windows create space and allow more light, making rooms appear larger. However, they also require structural work, which can be more time consuming and expensive.

Each style has its advantages and drawbacks. Your choice should match your home's architectural style, your personal preferences, and practical considerations like cleaning ease and ventilation.

Materials: wood, uPVC & Aluminium

The material of your new windows impacts not just the look but also the durability and maintenance requirements.

Wooden frames offer a timeless aesthetic, blending well with older houses in the UK. However, they need regular maintenance to prevent weathering.

uPVC frames are low-maintenance and offer good thermal insulation but might not suit the style of some traditional properties.

Aluminium frames are strong, slim, and long-lasting, suitable for a modern look and large window openings. They're also recyclable, making them an eco-friendly option.

When choosing the material for your window frames, consider factors like maintenance, energy efficiency, and how they complement your house's style.

Double or triple-glazing?

Glazing is a key factor in window performance. Double-glazed windows are standard in the UK, offering a balance between cost and efficiency. They provide good thermal insulation and noise reduction.

Triple glazing goes a step further, offering even better energy efficiency, which is particularly beneficial in colder regions or for houses with larger projects.

However, it's more expensive and can be heavier, requiring a stronger frame. The choice between double and triple glazing often comes down to your budget, the local climate, and your home's specific needs.

Remember, better-insulated windows contribute to a more comfortable living environment and can reduce energy bills over time.

Security features to consider

Your windows have a big role in your home security. When replacing windows, consider features like lock types, reinforced frames, and toughened glass. Multi-point locks offer higher security compared to standard latch locks.

Laminated or toughened glass is harder to break, adding an extra layer of security. Some windows also come with internal beading, making it difficult for the glass to be removed from the outside.

For homes in the Southeast or other areas where security is a prime concern, investing in these features can provide peace of mind.

Your window installer can provide tailored advice, ensuring your new windows enhance both the aesthetics and safety of your home.

Selecting a window company and installer

How to find reputable window installation companies

In the UK, selecting a reputable company for installing replacement windows is very important. Homeowners should start by researching local firms. Recommendations from friends or family offer a trustworthy source.

Online reviews and ratings on platforms like Trustpilot also provide valuable insights. Membership in trade associations, such as the Glass and Glazing Federation (GGF) or FENSA, indicates a company's commitment to industry standards.

You should check for proper insurance and certification, ensuring the company is qualified to handle window installations in British homes.

Questions to ask a window installer

Before meeting with a new window installer, prepare a list of questions. Enquire about their experience with installing windows in homes similar to yours. Ask about the types of windows they recommend and why. Clarify details about the installation process, including duration and steps involved.

Try to understand their policy on handling any unforeseen issues during installation. Ask for references or case studies from previous clients. This information helps in assessing their reliability and quality of work.

Understanding installation warranties and guarantees

Understanding the warranties and guarantees offered by window installers is important. In the UK, a standard warranty for replacement windows usually covers the product for a set number of years.

Guarantees often include workmanship, ensuring the installation is free from defects. Homeowners should clarify what is covered under the warranty and for how long.

It's important to know the process for making a claim, if issues arise. Also, check if the warranty is insurance-backed, providing coverage even if the installer goes out of business.

Preparing for the window installation process

Measuring for replacement windows

Accurate measurements must be taken for installing replacement windows. In the UK, measurements should be taken from the inside of the window frame. This ensures the new window fits precisely within the existing space.

Homeowners can measure themselves or, preferably, have the installer do it. Measurements include width, height, and depth, considering any irregularities in the frame.

Accurate measurements help avoid delays and ensure a snug, energy-efficient fit for the new windows.

Organising your space for installation day

Preparing your home for installation day ensures a smooth process. Clear the area around windows inside and out, providing easy access for installers. Removing curtains, blinds, and any wall decorations near windows prevents damage.

Informing neighbours about possible noise and disruption shows courtesy. Homeowners should also consider protecting floors and furniture with dust sheets. Preparing in advance facilitates an efficient and tidy installation process.

What to expect on installation day

On the day of installation, expect the installers to arrive at the agreed-upon time. They will start by laying dust sheets to protect your home's interior.

The process involves removing old windows, preparing the opening, and installing the new units. Communication from the install team about the progress and any issues encountered is standard.

Installation of each window may take several hours, depending on complexity and size. Homeowners should be prepared for some noise and disruption.

Protecting your home from dust and debris

During installation, protect your home from dust and debris. Installers usually use dust sheets and take measures to minimise mess. However, homeowners can take additional steps for protection.

Cover furniture and electronics in close proximity to the work area. Keep doors closed to contain dust to the work area.

After installation, a thorough clean-up by the installers is expected, leaving your home tidy and with your new windows ready to enjoy.

FAQs

How often should windows be replaced?

Replacing windows varies depending on several factors like material quality and climate. Most windows, when maintained well, last between 20 to 25 years. However, it's worth inspecting windows in an old house every 15 years. Signs like draftiness, difficulty in opening, and noticeable wear suggest it might be time to consider replacing your windows.

Can I replace windows in a conservation area?

In the UK, replacing windows in a conservation area requires adherence to specific regulations. Conservation areas often have restrictions to maintain the area's historical and architectural character.

It's advisable to consult local authorities before proceeding with window replacement in these areas. Often, the replacement window must match the style and material of the original.

Does window replacement increase home value?

Installing new windows can enhance a house's value, particularly if the old windows were inefficient or in disrepair. Replacing windows improves energy efficiency, security, and aesthetic appeal, which are attractive features to buyers. However, the return on investment varies depending on the type and quality of the windows installed.

How to handle broken glass during replacement?

Homeowners should keep the area clear and allow professionals to handle the removal and disposal of broken glass, ensuring a safe environment during the installation process. Be conscious of safety when dealing with broken glass during window replacement. Installers use dust sheets and take measures to prevent glass shards from scattering in the room.

By keeping these things in mind you can install replacement windows seamlessly.
