What to Expect During Your Window Installation: A Step-by-Step Guide

We get it—having work done on your home can feel overwhelming. But don’t worry; we’re here to make the process as smooth and hassle-free as possible. Whether replacing a few sash windows in London or tackling a complete home upgrade, we’ve broken down the key steps to help you feel confident and prepared every step of the way.

Before Installation: Getting Your Home Ready

A little preparation before we arrive will go a long way in ensuring a seamless installation. Here’s what you can do:

1. Clear the Work Area

Move any furniture or valuables near your windows to create space for our installers to work safely and efficiently. This also helps protect your belongings from accidental dust or damage.

2. Remove Window Coverings

Take down any curtains, blinds, or shutters before installation to avoid obstruction and keep them free from dust.

3. Let Us About Any Obstructions

If your windows have security grills, radiators, pipes, or electrical wiring nearby, let us know in advance. These will be flagged during our survey, and we’ll advise whether they need to be adjusted or removed to prevent delays.

Following these simple steps will prepare you for a stress-free sash window installation.

During Installation: Professional Care, Every Step of the Way

Once we begin, you can rest assured that we’ll treat your home with the utmost care and respect. Here’s what to expect:

✔ Safety First – For your safety and ours, we kindly ask that you avoid the installation areas while work is in progress.

✔ Protecting Your Home – We cover all working areas and access routes, taking extra care to safeguard anything that can’t be moved.

✔ Keeping Things Tidy – We clean as we go, ensuring your home stays as tidy as possible. At the end of each day, we’ll tidy up so you’re not left with any mess.

What If We Encounter Unexpected Issues?

While we aim for a flawless installation, older properties—especially in London’s period homes—can sometimes present unforeseen challenges.

Here’s how we handle them:

Structural Issues & Blown Plaster – Sometimes, issues like damp, subsidence, or dry rot only become visible once the old windows are removed. If this happens, we’ll advise on the best course of action, though we can’t be responsible for pre-existing defects.

Preserving Decorative Features – Period homes often have intricate mouldings and detailing that add character. We take extra care to protect these, but minor damage occasionally occurs.

After Installation: Final Touches & Next Steps

Once your new sash windows are installed, here’s what to expect:

1. Ready for Decoration

Your new windows will be installed to a paint-ready finish. If necessary, light sanding may be required before painting.

2. Cleaning Up

While we minimise dust as much as possible, some will settle after installation. Once the dust settles, we recommend giving the room a deep clean and keeping the windows open to ventilate any lingering fumes from installation solvents.

3. Addressing Snagging Issues

If any minor adjustments are needed—such as replacing a handle—our aftercare team will take care of them promptly.

Investing in sash windows in London is a fantastic way to improve your home’s energy efficiency, security, and traditional charm. Our expert installation team ensures a seamless process from start to finish so you can enjoy your beautifully crafted windows with total peace of mind.
