Is it possible to retrofit Electric Shutters into Existing Windows?

You are asking the right question if you are looking at your existing windows and are wondering whether you can get the electric shutters without tearing everything down and having to build it all over again. The answer to this is yes, under most circumstances you can. The more detailed response is a little more on what is and what can become problematic.

The Meaning of Retrofit

Retrofitting refers to the process of adding something new to the existing one instead of constructing the entire one. This is typically done with shutters installed either to your existing window frames or the wall that surrounds them, and the electric mechanism and controls are added.

This contrasts with new-build installations whereby all of this is planned and fitted as the building is constructed. The retrofit jobs are working around what already exists and that too comes with its own problems.

The Good News of the Modern Systems

There is an improvement in electric shutters over the last ten years. The manufacturers are aware that the majority of their clients are not starting their building works from scratch. They are individuals who have good windows and would like to put shutters one without making a construction site.

This is the reason why the majority of systems are being created to be retrofit work. The motors are smaller and compact in nature compared to the past. The mounting brackets can be fitted to a variety of frame depths and wall type. The battery powered ones imply that you do not necessarily have to drag cables through the walls, or obtain the services of an electrician.

The external shutters normally attach to the wall over the window or on the frame itself. The internal ones are located in the recess of a window or on the wall face. They both can be retrofitted, but outside shutters typically require additional structural effort.

Where You Might Hit Problems

Not all windows fit and it is better to find this out before you go too deep along the line.

Old windows have weak or rotten frames that may not support the weight or fixing points. When your frames are rotten or crumbling, then they must be sorted out. You can not screw a shutter system to timber that is disintegrating.

Listed buildings are an entirely different thing. External shutters will require planning permission, and possibly internal shutters as well, where they can be seen on the street. Rules are also present in conservation areas. Before you spend a penny make sure to check with your local planning authority.

The size and shape of the windows are also important. Rectangular windows are simple and standard. Bay windows, arched windows or objects to have unusual proportions may require custom solutions, so it will be associated with higher costs and lead time.

The Installation Process

Measure the window, have the shutters made to fit, and then put them to the frame or recess. The electric motor is installed in the top rail, and in the case of going wireless that is just about it. Wired systems require a cable to be installed to a switch or connection to your home automation system.

External shutters imply increased labour. You are drilling through external walls and this means that you are dealing with new materials, which include brick, render, cavity walls. The shutter box (on which the rolled-up shutter is stored when it is not being used) must be secured. In case you are laying cables, they will need to be water resistant and be placed in a safe manner.

A good installer will look around your windows and will tell you what he can do. They can tell you about any structural issues, whether you require planning permission and what the installation will entail.

What is the cost and how long

Retrofit installations are normally expensive than new-build work since you cannot be sure of what you are going to be dealing with when you begin. An installer may give a price depending on the assumptions he/she has regarding your wall construction and then find out that it is not like that after arriving.

Internal electric shutters will cost between £300 and £800 each window and external roller shutters will cost much more (between 800 and 2000 depending on size and design).

A small number of windows (typically one or two days) are typically installed, or more time is required to install an entire house or do extensive electrical installation.

Making It Work

It is always advisable to have a good survey first before committing oneself to anything. Installing a good installer will measure up, check your walls and frames, talk with you about your options, and provide you with a realistic quote that will not blow up when work gets underway.

The majority of windows can be retrofitted with the appropriateness of the shutters. It is simply a matter of fitting the system to what you really have, and not attempting to make it fit a system that is not at all suitable.
