Bay & Bow Windows

More light. Bigger feel. Frontage that looks the part.

Bay and bow windows open up a room with extra daylight and a wider view. They add presence to the front elevation and make lounges and dining rooms feel larger without changing the footprint. We make and fit bay and bow windows across Grantham, Stamford, Sleaford, Newark, Bourne, Melton Mowbray and nearby villages.

Why Choose a Bay or Bow Window

Brighter rooms
Angled or curved frames pull in more natural light.
Sense of space
Projection creates depth so lounges and front rooms feel bigger.
Kerb appeal
Classic feature that lifts the whole frontage.
Warm and quiet
Modern frames, tight seals and high-performance glazing improve comfort.
Flexible layouts
Mix fixed panes with side-hung or top-hung openers where you need airflow.

Bay vs Bow: What is the Difference

  • Bay window
    Usually three or five sections set at angles. Strong, defined lines. Great for front lounges and dining rooms.

  • Bow window
    Four or five sections set on a gentle curve. Softer look with a continuous sweep of glass.

Structure, Strength and Weathering

A great bay or bow is not just about the frames. It needs proper support and weathering so it lasts.

  • Support and loads
    We check whether the bay carries any weight from above. Where needed, we include poles, jacks or structural posts in the quote. No guesswork on the day.

  • Tie rods and canopies
    Existing tie rods, gallows brackets or canopies are inspected and renewed where required for safety and stability.

  • Base and cill
    We assess the under-bay area, cill projection and drainage so water sheds properly and seals stay tight.

  • Sealing and trims
    Clean lines, neat mastic work and matching trims to prevent draughts and water ingress.

Energy, Security and Everyday Comfort

Warmth

Low-e coatings, argon-filled units and warm-edge spacers help achieve low U-values so the front room stays comfortable in winter.

Noise

Optional acoustic or laminated glass and tight seals reduce road noise on busier streets.

Security

Multi-point locking and robust hinges as standard. Laminated glass available for vulnerable panes.

FREQUENTLY ASKED QUESTIONS

Bay & Bow Windows

If we are converting a flat window to a projecting bay, there is usually light building work for the base and roof or canopy. We will outline this clearly in the quote or coordinate with your builder.

Like-for-like replacements usually do not need permission. New projections or changes in appearance may need approval, especially in conservation areas. We will advise before you commit.

Some do. We check at survey. If support is needed, we include poles, brackets or structural posts in the price so the job is safe and compliant.

Yes. We can mirror Georgian or Victorian layouts with astragal bars so the frontage stays authentic.

Modern frames and glazing deliver better insulation than older units. You should feel fewer draughts and a more even temperature.

Warm-edge spacers, low-e glass and correct ventilation reduce the cold band at the edge of the glass that causes condensation.
