Is your sliding patio door hard to open, letting in draughts, or refusing to lock? You're not alone — these are some of the most common faults we repair across Bournemouth, Poole and Christchurch.

At ACP Windows we specialise in repair-first solutions for French doors, sliding patio doors and patio doors in uPVC and aluminium. Our teams carry all common roller types, use top-quality suppliers for replacement parts, and focus on repairing rather than replacing — saving you time, money and stress.

Common problems we fix

Whether your door is stuck, draughty or unsafe, we’ll identify the cause and fix it properly. The faults we repair most often include:

• Worn or broken rollers on sliding doors
• Dropped doors due to weight or age
• Misalignment after years of movement or expansion
• Failed locking systems that no longer secure properly

Because patio doors are heavy and used frequently, even small issues quickly become big problems if left untreated.

What makes our repairs different

Unlike many companies who jump straight to replacements, we’re a repair-first team. That means:

• We investigate properly — and fix what can be fixed
• We carry all common rollers, handles and lock parts
• We source hard-to-find and obsolete parts via our specialist suppliers
• We can suggest suitable alternative products when an exact match isn’t available
• We handle both sliding and locking mechanisms

Even if someone else says it can’t be repaired — it’s always worth asking us.

Clean, careful and respectful

Patio door repairs can be heavy-duty work — but that doesn’t mean they should make a mess. We use:

• Shoe covers and floor protection indoors
• Grass, patio or decking protection outdoors
• Vacuuming and surface wipe-downs as standard after every job
• Teams of two where required

Clean, tidy and respectful — it’s all included in the service.

How long do repairs take?

• Roller replacements are usually completed on the first visit
• Track replacements, specialist locks and non-standard parts may require a second visit, but parts are normally on next-day delivery
• We’ll always explain what’s needed and agree a plan and price before we begin

Who we help

We regularly carry out patio and sliding door repairs for:

• Homeowners
• Landlords and rental properties
• Letting agents

The repairs we carry out

• Handle and lock replacements — Upgrade or replace worn handles and locks to improve security and ease of use on your sliding or patio doors.
• Doors that are hard to slide — Realignment and track adjustments so your sliding doors glide smoothly without sticking or resistance.

After the repair

Once fixed, most customers are relieved they didn’t need a whole new door, reassured that their home is secure again, and surprised at how smoothly the door now moves. Many of the doors we repair haven’t been locked in years — and feel like new after a proper fix.
