What’s Actually Included in the Price of a New Sash Window? (And What’s Not)

Are You Confused About What You’re Really Paying for in a Sash Window Quote?

When you’re comparing sash window quotes, do you ever wonder why the prices vary so much, even when the windows look the same?

Worried About Hidden Costs After Installation?

Many homeowners only find out after installation that their quote didn’t include key elements like painting, architraves, or even proper sash weights. That leads to extra bills, unfinished work, and plenty of frustration.

You Deserve Total Transparency From the Start

At Novells Sash Windows, we believe you shouldn’t have to read between the lines of a quote. That’s why every window we install is fully finished, fully fitted, and designed to last, no hidden extras, no fine print.

In This Article, You’ll Learn Exactly What’s Included (and What’s Not)

We’ll walk you through what’s included in our typical sash window installation, what’s priced separately, and how to compare quotes with confidence, even if you don’t buy from us.

What’s Included: Your Fully Finished Box Sash Window

1. The New Box Frame & Double-Glazed Sashes

  • Handcrafted Timber Box Frame made from premium, sustainably sourced Redwood (or Accoya if requested).
  • Double-glazed timber Sashes are fully draught sealed and designed to match period property styles with traditional glazing bars.
  • Authentic Detailing, including horns, mouldings, and profiles that stay true to your home’s architecture.

2. Fully Painted in The Workshop, No On-Site Painting Needed

  • Factory spray-finished with a durable, long-lasting microporous paint system.
  • Only an extra top coat to the inside frame and architraves is required on site, which saves time, avoids mess, and ensures a flawless finish.
  • Choose any colour, including dual-colour (inside/outside) combinations.

3. A Complete Installation, Not Just the Window

  • New hardwood window sill – fitted as part of the new frame.
  • New internal architraves and linings – for a clean, finished look inside your home.
  • All new sash weights and cords – correctly balanced for smooth, long-lasting operation.
  • Quality ironmongery – choose your finish for sash lifts, fasteners, and security stops (e.g., polished chrome, satin chrome or brass).
  • Draught sealing throughout the system for improved energy efficiency.
  • Removal and disposal of your old windows and frames, done for you.

 

 

What’s Not Included and Why

We’re up front about what’s priced separately, so there are no surprises.

  • Scaffolding, if needed for access (e.g. dormers or windows in loft conversions) we’ll clearly itemise this in your written estimate.
  • Internal redecoration of the wall surfaces surrounding the frame.
  • Specialist glazing options like stained, leaded, or patterned glass are available on request and quoted separately.

Why This Matters: The Novells Difference

Most companies give you a window; we give you a finished installation.

It’s not uncommon for homeowners to realise after the fact that their installer didn’t include:

  • Internal finishings (like bullnose, linings or architraves)
  • Painting or sealing
  • Proper sash weights or draught-proofing

With Novells Sash Windows, every window is complete the day we leave, fully painted, professionally fitted, and built to last for decades.
