About Novells

Most homeowners with beautiful period properties share the same challenge:

They love the charm, character and history of their home, but they’re tired of the draughts, condensation, noise and heat loss caused by old single glazed windows and doors.

At Novells, we specialise exclusively in brand-new, fully finished timber box sash windows and French door sets built for period homes across London and the surrounding areas. Our mission is simple:

To help homeowners upgrade their comfort, efficiency and security without losing the original character that makes their home special.

If it’s not a new timber sash window or French door set, we don’t do it.

That level of focus means we’re able to deliver what matters most: accuracy, longevity, beauty and reliability.

Why Homeowners Choose Novells Sash Windows

When it comes to replacing windows in a period home, the stakes are high.

The wrong product, material or installation approach can permanently damage the character of your home, or worse, leave you with ongoing issues that cost thousands to fix later.

When you work with us, you’ll always know exactly what you’re getting, what it costs, and why it matters, before any decisions are made.

That’s why homeowners choose Novells:

Specialists in new heritage-style windows and doors only

Conservation sensitive designs that match original architecture

Fully workshop-painted and ready to install, no site painting

Engineered timber options, including Redwood & Accoya

Traditional detailing with modern energy performance

20+ years of experience working on London period homes

Family-owned, reputation led, no sales pressure

What We Believe

Quality beats shortcuts, every time

If it’s not built to last, we won’t install it

Customers deserve honesty, not uncertainty

Heritage homes should be improved, not altered

Our goal is not to be the cheapest; our goal is to be the company you’re still grateful you chose 20 years later.

Meet the Owner, Philip Novell

I grew up around traditional joinery and have spent over two decades helping homeowners across London replace their ageing sash windows with something they can be genuinely proud of.

Over the years, I learned something important:

Most frustrations in home improvement come from unclear communication, unclear expectations, and unclear outcomes, not the product itself.

So, I built Novells differently.

Instead of offering every service under the sun, we focus on one thing done exceptionally well: premium new double-glazed timber sash windows and French door sets, built and fitted properly.

I still personally oversee the details that matter:
the design, the measurements, the materials, the fit, and most importantly, how the customer feels at each step.

My guiding promise is simple:

“If I wouldn’t install it in my own home, I won’t install it in yours.”
