Glass Replacement in Lincolnshire

Serving Lincolnshire, Nottinghamshire, Cambridgeshire, Norfolk & Rutland

Misted, cracked, or broken double glazing units are one of the most common glazing problems in UK homes — and one of the most straightforward to fix. If your sealed units have failed (shown by condensation or misting between the panes), or if a pane has been cracked or broken, there is no need to replace the entire window frame. Pilgrim uPVC Specialists Ltd provides a fast, affordable glass replacement service across Boston, Lincolnshire and the surrounding area, fitting new energy-efficient sealed units directly into your existing frames.

What We Offer

Misted Unit Replacement

When the seal on a double glazed unit fails, moisture gets between the panes causing permanent misting. We replace the failed unit with a new A-rated sealed unit — no need to replace the frame.

Broken & Cracked Glass

Accidental damage to a window or door pane? We can replace individual panes quickly and safely, using toughened safety glass where required by Building Regulations.

Energy Upgrade Glazing

Upgrade your existing frames from standard double glazing to high-performance warm-edge spacer units with argon gas fill — improving your home's energy rating without replacing the frames.

Conservatory Roof Glass

Replace failed, cracked, or discoloured conservatory roof glass panels. We can also upgrade polycarbonate roofs to self-cleaning or solar control glass.

Decorative & Obscure Glass

Replace bathroom, door, or privacy glass with a wide range of obscure, frosted, or decorative glass options to suit your style.

Toughened & Laminated Safety Glass

Where Building Regulations require safety glass (low-level glazing, doors, and certain windows), we supply and fit toughened or laminated safety glass to the correct specification.

Frequently Asked Questions

How do I know if my double glazing unit has failed?

The most common sign of a failed sealed unit is misting or condensation between the two panes of glass that cannot be wiped away. This means the hermetic seal around the edge of the unit has broken down, allowing moisture-laden air to enter. A failed unit cannot be repaired — it must be replaced.

Can you replace just the glass without replacing the whole window?

In most cases, yes — provided the frame itself is in good condition. We measure the existing unit and supply a new sealed unit to the same specification, which is then fitted directly into the existing frame. This is significantly cheaper than replacing the whole window.

How long does glass replacement take?

Most glass replacement jobs can be completed in a single visit. Lead times for new units are typically 1–2 weeks from order confirmation.

Is toughened glass required in all windows?

No — toughened or laminated safety glass is required by Building Regulations in specific locations, including glazing within 800mm of floor level, glazing in doors and side panels adjacent to doors, and certain bathroom windows. We will advise you on the correct specification during your survey.

Do you replace glass in conservatory roofs?

Yes — we can replace individual glass panels in conservatory roofs, including standard float glass, self-cleaning glass, and solar control glass. We can also advise on upgrading from polycarbonate to glass.
