Everything you need to know about our high-security products, accreditations, and professional installation process.

General & Process

Q.Do you provide a free survey and quote?

A.

Yes, we offer a free, no-obligation site survey. One of our experts will visit your property, take precise measurements, and discuss your options before providing a detailed quote tailored to your needs.

Q.What are your standard lead times?

A.

Our typical lead time for standard doors and windows is 3-4 weeks from survey to installation. Custom colors (RAL colors) or specialized designs usually take 5-6 weeks. We provide a confirmed date once your order is processed.

Q.Where do you provide your services?

A.

We primarily serve South Yorkshire and the surrounding areas, including Barnsley, Sheffield, Rotherham, Wakefield, and Doncaster. We cover all local towns—if you're unsure if we cover your area, just ask!

Accreditations & Standards

Q.What is ASSURE Certification?

A.

ASSURE is a lead accreditation body in the UK window and door industry. Being ASSURE certified means our installations meet strict technical standards, comply with building regulations, and are carried out by vetted professionals.

Q.Are your installations compliant with Building Regulations?

A.

Yes, every installation we perform is fully compliant. As an ASSURE accredited installer, we handle the certification and paperwork to ensure your home meets all current safety and thermal efficiency standards.

Q.Do you provide insurance-backed guarantees?

A.

Absolutely. All our major installations come with an insurance-backed guarantee, providing you with long-term peace of mind even beyond our standard workmanship warranty.

Products & Customization

Q.What color and finish options do I have?

A.

We offer a vast range of standard colors (like Anthracite Grey, Chartwell Green, and Black) as well as any custom RAL color. You can also choose from various woodgrain textures and 'dual color' options (different colors for the inside and outside).

Q.Can I choose my own glass designs?

A.

Yes, you can customize your glass with frosted, obscured, leaded, or decorative patterns. We also offer high-performance triple glazing for maximum thermal insulation.

Q.What are 'SleekSkin' doors?

A.

SleekSkin is our exclusive range of smooth-finish contemporary doors. They provide a modern, minimalist look while retaining the high-security and thermal efficiency of a traditional composite door.

High-Security Locks

Q.What is an APECS AP High-Security cylinder?

A.

The APECS AP is a 3-star BSI Kitemarked cylinder, the highest rating available. It features unique anti-snap, anti-pick, and anti-drill technology, designed to stay locked even if the front of the lock is snapped off.

Q.Can I upgrade my existing door locks to APECS?

A.

Most likely, yes. We can replace standard Euro cylinders on almost any uPVC or composite door with a high-security APECS upgrade, significantly improving your home insurance compliance.

Q.What is a BSI 3-Star Kitemark?

A.

The 3-Star Kitemark is the gold standard for lock security in the UK. It indicates that the cylinder has passed rigorous manual attack testing, including snapping, drilling, and bumping.

Smart Home Security

Q.What is a Tedee Smart Lock?

A.

Tedee is the world's smallest and strongest smart lock. It allows you to unlock your door via smartphone, share digital keys with guests, and even set it to auto-unlock as you approach with your bags full of shopping.

Q.Does a smart lock still have a physical key?

A.

Yes. Our Tedee and Kubu smart systems are designed as 'smart upgrades' to high-quality physical cylinders. You can always use a physical key as a backup if your phone is unavailable.

Q.How does the Kubu Smart Sensor work?

A.

Kubu integrates directly into your door. It allows you to check if your door is locked or unlocked from anywhere in the world via an app, and can even alert you if you leave home without locking up.

Repairs & Finance

Q.How does the Kanda finance option work?

A.

Kanda allows you to spread the cost of your property improvements with flexible payment plans. You can apply online or during our visit, and you'll get an instant decision.

Q.Do you offer repairs, or only full installations?

A.

We specialize in full installations but also offer a range of repair services including glass replacement (misted units), lock upgrades, and fixing faulty handles or hinges.
