Double Glazing Windows Morden

We make and fit double glazing windows in Morden for homeowners who want warmer, quieter rooms and frames that suit the style of their house. On this page you will find the window types we fit locally, how we make and install them, what drives the cost and how to pick the right style for your home.

Every window is made to measure and fitted by our own FENSA-registered team. Each one comes with a 10-year guarantee. We work right across Merton, and our main double glazing windows page covers the full range. Here we focus on what matters for homes in Morden.

Window Styles That Suit Local Homes

The best window for your home is the one that matches its age and look. We fit four main styles, and each one suits a different kind of house.

• Casement windows. Side-hung or top-hung sashes in a fixed frame. They suit most post-war and modern homes, and they are the most popular choice. See our casement windows page.
• Flush casement windows. The sash sits level with the frame, like a timber window from the past. They suit cottages, 1930s homes and anyone who wants a neater, cleaner face. Read more about flush casement windows.
• Sash windows. Vertical sliders for Victorian and Edwardian homes. They keep the period look but add modern glass, seals and locks. Our sash windows page explains the options.
• Bay and bow windows. Several frames joined at an angle or on a curve. They add light and floor space and are common on older terraces and semis.

Tilt and turn windows are also an option for flats and upper floors. They open inwards, which makes them easy to clean from inside.

Frame Materials Compared

We fit frames in uPVC, aluminium and timber. Each has its own strengths.

• uPVC is low cost, low upkeep and warm. Modern profiles come in woodgrain foils and colours such as grey, cream and black, not just white.
• Aluminium gives slim frames and large panes of glass. A thermal break inside the frame stops the cold getting through. It suits modern homes and wide openings.
• Timber looks right on older homes and in conservation areas. Factory-finished frames need a fresh coat of paint or stain every few years.

In Morden, many people choose uPVC with a woodgrain finish on the street side. It gives a softer look than plain white and needs very little care.

Glass, Warmth and Noise

All our windows use A-rated sealed units as standard. A typical unit is 28mm wide, with two panes of glass, low-E coating, argon gas and a warm-edge spacer bar. That gives a whole-window U-value of around 1.2 to 1.4 W/m²K, which meets the Part L limit for replacement windows.

You can upgrade the glass to suit the room:

• Acoustic glass uses laminated panes of different thickness. It helps on main roads and near railway lines.
• Toughened or laminated safety glass is required in low panes, near doors and in bathrooms.
• Obscure glass gives privacy in bathrooms and on landings.
• Triple glazing adds a third pane for the best U-value, around 0.8 W/m²K. Read our triple glazing page to see if it suits you.

Trickle vents can be fitted in the head of the frame to keep fresh air moving. Building Regulations may require them where the old windows had them, or in kitchens and bathrooms.

Planning and Building Regulations

Most homes can have new windows without planning permission, as long as they look much like the old ones. The rules change in a few cases:

• Conservation areas. Some streets have an Article 4 direction. This can mean you need consent to change the style or material of front windows.
• Listed buildings. You need listed building consent for any change. Slim double glazing in timber or secondary glazing may be allowed.
• Flats. Your lease may need the freeholder's consent first.

All replacement windows must meet Building Regulations for heat loss, safety glass, fire escape and air flow. Because we are FENSA registered, we sign off the work ourselves. You get a certificate when the job is done, so there is no need for a separate visit from building control. When you buy from any firm, check they are with FENSA or Certass.

How We Make and Fit Your Windows

We survey first, then make every frame to the exact size of your opening. Frames are built to order, glazed and checked before they leave the factory.

On fitting day, we cover floors and furniture, then take out the old frames one at a time. Each new frame is fixed into the wall, packed and sealed. We fit the cills and trims, then make good the inside and outside. Most houses take one to three days. You are never left with an open hole overnight.

The full journey, from first visit to aftercare, is on our how we work page.

What Drives the Cost of Double Glazing Windows

We do not list fixed prices here, because every home is different. The main things that change the price are:

• The size and number of windows.
• The style, with sash and flush casement costing more than standard casement.
• The frame material and colour.
• The glass spec, such as acoustic or triple glazing.
• Access, such as upper floors that need a tower or scaffold.
• Making good, such as new cills or repairs to rotten lintels.

After a free survey, you get a written, fixed quote that lists each window and every extra. Book yours on our get a quote page.

Looking After New Windows

Modern frames need very little care. Wipe uPVC and aluminium frames with warm soapy water a few times a year. Keep the drain holes in the bottom of the frame clear. Put a drop of light oil on the hinges and locks once a year.

Timber frames need a check each spring. Touch up any chips in the paint before water gets in. If a sash starts to drop or a lock gets stiff, call us. Most small fixes take a few minutes.

Frequently Asked Questions

Can you fit double glazing in a conservation area or listed building?

Often, yes. In a conservation area, we match the look of the old windows, such as flush casements or sash windows in a woodgrain finish. Some streets need consent first. For a listed building, you need listed building consent. Slim timber double glazing or secondary glazing is often the answer. We can help you with the drawings and spec for the council.

Do new windows make the house stuffy?

Not if they are set up right. New windows stop draughts, so the air changes less on its own. Trickle vents in the frame let a small, steady flow of fresh air in, even when the window is shut. Opening a window for a few minutes each day and using kitchen and bathroom fans also keeps the air fresh and helps stop condensation.

What upkeep do timber and uPVC frames need?

uPVC needs a wipe with soapy water a few times a year, clear drain holes and a drop of oil on hinges and locks. Timber needs the same, plus a check of the paint each spring. Expect to repaint or re-stain every few years. Factory-finished timber lasts longer between coats than frames painted on site.

Can you add smart or electric opening to new windows?

Yes, for some window types. Electric openers suit high windows, roof lights and rooms where the window is hard to reach. Sensors that tell an alarm system when a window is open can also be fitted. Ask at the survey, as the frame and locks need to be ordered to suit the opener.

What happens to the guarantee if you sell your home?

Our 10-year guarantee stays with the house, not with you. When you sell, pass the guarantee papers and the FENSA certificate to the buyer. Their solicitor will often ask for the certificate anyway, as it shows the windows meet Building Regulations. If you have lost it, we can arrange a copy.
