Protect Your Home with High-Quality, Professionally Fitted Fascias and Gutters

At A. Gallagher & Son, we supply and install durable guttering and fascia systems for homes and businesses across North Wales — including Gwynedd, Anglesey, Conwy, and beyond. Whether you’re replacing old, worn-out parts or upgrading to a more modern finish, we offer dependable solutions that keep your property protected from water damage.

We provide:

• Full fascia and soffit replacement
• Gutter upgrades in uPVC, aluminium, or galvanised steel
• Repairs to leaking, misaligned or damaged sections
• Downpipe installation and replacement

Chimney Repair Specialists in North Wales

Preserving the Character and Safety of Your Roofline

A. Gallagher & Son provides expert chimney repair services for residential and commercial properties throughout North Wales — including Gwynedd, Anglesey, Conwy, and surrounding areas. Whether your chimney is leaking, leaning, or crumbling, we deliver high-quality repairs that restore both structure and appearance.

Repairing Damage Before It Spreads

Chimneys are one of the most exposed parts of your home — facing wind, rain, frost, and heat all year round. Over time, that exposure can lead to cracked brickwork, loose render, faulty flashing, or damaged pots — all of which can pose safety risks or cause water to seep into your property.

We handle:

• Repointing and brick replacement
• Chimney stack repairs and rebuilds
• Flashing and leadwork renewal
• Chimney cap and cowl replacement
• Leak detection and water ingress prevention
• Restoration of decorative or traditional features

Skilled Tradespeople, Professional Results

Our team includes experienced roofers and brickwork specialists who understand how to repair chimneys safely and correctly — whether it’s a minor fix or a full rebuild. We use the right materials for the age and style of your property, and we’re careful to work cleanly and efficiently with minimal disruption.

We also inspect the surrounding roof area, so if your chimney issues are linked to tile damage or worn-out leadwork, we can carry out any necessary repairs at the same time.

Serving Gwynedd, Conwy, Anglesey and Beyond

From older stone-built chimneys to modern brick stacks, we’ve repaired chimneys on everything from rural cottages to townhouses and business premises. Based in Bangor, we cover all of North Wales and are happy to provide advice, inspections, and quotes with no obligation.

Velux Window & Roof Light Installation in North Wales

Bringing Light and Fresh Air Into Your Loft or Extension

At A. Gallagher & Son, we professionally install roof lights and Velux-style windows across North Wales — including Bangor, Anglesey, Conwy and surrounding areas. Whether you’re converting a loft, adding an extension, or simply looking to brighten a dark space, we’ll help you choose and fit the right roof glazing for your needs.

Expert Installation — Branded or Bespoke

Velux is one of the most well-known names in roof windows, and we’re experienced in fitting the full Velux product range. But we’re not limited to one brand — we also install other high-quality roof light systems tailored to your space, your roof structure, and your budget.

Our services include:

• Velux window supply and installation
• Flat or pitched roof light fitting
• Manual or electric opening options
• Flashing kits and watertight integration
• Internal trimming and finishing
• Repairs or replacements for existing roof windows

Whether it’s a single top-hung window or a larger fixed-pane roof light, we’ll make sure it’s installed correctly, safely, and in keeping with your property.

Trained Roofers — No Subcontracted Fitters

Unlike some firms, our installations are carried out by skilled roofers — not general trades or window contractors. That means your roof stays watertight, properly ventilated, and structurally sound. We take the time to ensure flashing and sealing are done to the highest standard, reducing the risk of leaks or future repairs.

If your new roof window is part of a wider renovation, we can work alongside builders or interior trades to ensure a smooth project.

Covering All of North Wales

Based in Bangor, we provide Velux and roof light installation throughout Gwynedd, Conwy, Anglesey and surrounding areas. We work on homes, holiday lets, extensions, converted lofts and more — always with a focus on clear communication, quality materials, and tidy workmanship.

Let the Light In — Safely and Stylishly
