We make and fit double glazing doors in Merton Park, from front doors and back doors to French, patio and bifold sets. You get a door made to the exact size of your opening, fitted by our own team and backed by a 10-year guarantee.
This page looks at doors for homes in Merton Park in particular: the kind of houses we work on here, which door styles suit them and what to think about before you choose. For the full range, see our main double glazing doors page. For windows and other work in the area, go back to our Merton Park glazing page, or see all our double glazing across Merton.
Doors in Merton Park: what we see locally
- Typical homes: Edwardian houses of the John Innes estate, Victorian villas and interwar semis
- Streets we fit on: Mostyn Road, Dorset Road and Sheridan Road
We match the door to the age and style of the house. A front door that suits a new estate home can look out of place on a period terrace, and the other way round.
Types of Door We Fit
Most homes need more than one kind of door. These are the main types we make and fit.
- Composite front doors: a solid core with a tough, grained skin. They look like painted timber but need far less care.
- uPVC front and back doors: a lower cost choice with good locks and good heat loss figures.
- Aluminium entrance doors: slim, strong and modern, with a wide choice of colours.
- French doors: a pair of doors that open out to the garden, with no post in the middle.
- Sliding patio doors: large panels that glide past each other, so they take no room to open.
- Bifold doors: panels that fold and stack to the side, to open up most of a wide wall.
- Stable doors: split in two across the middle, so the top can open on its own.
Choosing a Door to Suit Your House
Start with how the door will be used and where it sits. A front door needs to look right from the street and keep the house secure. A back door or garden door needs to let in light and stand up to wind and rain.
Some simple rules help:
- Period homes: a composite or timber door with panels, a fanlight and a classic knocker often looks best.
- Post-war and modern homes: clean, flat doors in grey, black or white suit the simple lines.
- Small rear openings: a single door or a pair of French doors gives the best view for the width.
- Wide rear walls: sliding or bifold doors make the most of the space.
If you live in a conservation area, the council may ask that a front door matches the old style. We can help you check this before you order.
Glass, Heat Loss and Noise
Every glazed door we fit uses a sealed double glazed unit. Each unit has low-E coated glass, argon gas between the panes and warm-edge spacers. Together they keep heat in and cut the cold spot round the edge of the glass.
Under Part L of the Building Regulations, a new door must reach a U-value of 1.4 W/m²K or better. Our doors meet that, and the exact figure for your door is on your quote. If you live on a busy road, we can use laminated glass to cut traffic noise. For bathrooms and front doors, we offer a wide range of obscure and decorative glass.
All glass in a door, and any pane within 800mm of the floor, is toughened or laminated safety glass. It is far stronger than standard glass, and safer if it breaks.
Locks and Security
A good door should be hard to force. Every door we fit has a multi-point lock that bolts into the frame at several points when you lift the handle and turn the key.
On top of that, we fit:
- Anti-snap cylinders that resist the most common break-in method
- Steel keeps fixed into the frame
- Glass beaded on the inside, so it cannot be removed from outside
- Hinge bolts and anti-lift blocks on patio and French doors
Many of our doors can be made to the Secured by Design standard if you ask. That is the police-backed standard for door security.
Colours, Hardware and Finishing Touches
The finish is what you and your visitors see every day. Our composite and uPVC doors come in a wide range of colours, from classic black and white to green, blue, red and grey. You can pick one colour outside and white inside, to keep the hall light.
You can also choose:
- Chrome, gold, black or brushed steel handles and knockers
- Letter plates, spy holes and house numbers
- Side panels and fanlights to bring more light into the hall
- Smart locks that open with a code or a phone
Thresholds, Steps and Level Access
The base of a door matters as much as the frame. A standard threshold has a small upstand that keeps rain and draughts out. A low threshold is easier to step over, and suits buggies, wheelchairs and older family members.
On a back door that opens onto a patio, we check the ground level outside. Water must run away from the door, not towards it. Where the patio sits high, we may fit a drain channel in front of the sill. On a front door, we look at the step and path, and make good any brickwork we disturb.
What Drives the Cost of a New Door
We do not list fixed prices, because each door is made to measure. These are the main things that set the cost:
- Type of door: a single back door costs far less than a large bifold set.
- Material: composite and aluminium cost more than uPVC.
- Glass: decorative, laminated or triple glazed units add to the price.
- Side panels and fanlights: more frame and glass mean more cost.
- Hardware and colour: dual colours, smart locks and premium handles add up.
- Building work: a wider opening, a new lintel or a new step all take extra time.
Every job gets a free survey and a written, fixed quote. The quote lists the door, glass, locks and any building work, and sets out the payment stages. You can book your free survey here.
Our full process, from survey to aftercare, is set out on our how we work page. In short, we measure, make the door to size and fit it in a day, then check it locks and seals well before we leave.
Frequently Asked Questions
Will new double glazed doors affect your Wi-Fi or phone signal?
For most homes, no. Standard low-E glass has a very thin metal coating that can weaken some signals a little, but the effect is small. Walls and floors block far more signal than a door does. If your router is near the front door, and you notice a drop, moving it a short way into the house will often sort it out.
Can a new door be fitted around an existing alarm sensor?
Yes. We note any alarm contacts at the survey. On the day, we take the sensor off with care and refit it to the new frame, or leave the cable ready for your alarm firm. Some doors can take a hidden sensor inside the frame. Tell us your alarm make, and we will plan around it.
Which cleaning products are best avoided on the glass and frames?
Avoid scouring pads, wire wool and harsh cleaners with bleach or ammonia. They can scratch the glass and dull the frames. Use warm water with a little washing-up liquid and a soft cloth. A standard glass cleaner is fine for the panes. The low-E coating sits inside the sealed unit, so you cannot damage it from outside.
Will the colour of a door fade over time?
Good quality composite and uPVC doors are made to resist fading, and the colour is backed by the maker's guarantee. Darker colours on a south-facing door take the most sun, so they may change very slightly over many years. Wash the door a few times a year to keep the finish clean and bright.
Does a new door affect your home insurance?
Most insurers want front and back doors to have a good lock. Our multi-point locks and anti-snap cylinders meet the usual needs. Some insurers may ask for a British Standard lock or Secured by Design. Check your policy terms, and keep your FENSA certificate and guarantee papers safe in case you are asked for them.
