How to Choose the Right Company to Fit your Sash Window

Replacing your home's windows can have a dramatic effect on its aesthetics and can give a completely different look to its exterior. Many people believe the windows of a house give it 'personality' – similar to how the lights on the front of a car add character.

However, while changing or replacing your home's windows is a relatively complex task at the best of times, if you're looking to fit sash windows, it can get considerably trickier, requiring the skills of an experienced sash-style window fitter.

What are sash windows? 

Sash windows typically feature two 'sashes' which slide against one another to allow a vertical opening and closing mechanism. The sash style was used in older, more traditional Georgian, Victorian, and Edwardian buildings. They are often a requirement in listed or protected buildings where newer styles usually aren't permitted. 

Choosing the right sash window fitter

Due to their complex sliding mechanism, fitting sash windows require more specialist skills than those needed to install other types of windows, so you should try to find a fully qualified and experienced installation company. Often asking family or friends might help you find a recommended sash window company but, if not, here are a few questions you should ask before commissioning a firm to perform the work: 

History of fitting sash windows: As mentioned above, sash windows are considerably more complex to fit than other types, so be sure to check a firm has a track record of installing the sash style. Also, ask to see professional window-fitting qualifications and certifications relevant to your state or country. Lastly, you should request proof of a company's insurance, including liability cover, in case they cause damage to your property. 

Ask to see previous work examples: Most reputable companies will be more than happy to show you previous jobs and models of similar projects. Indeed, trusted firms will typically have a showcase section or detailed case studies on their website explicitly outlining past work. If they don't, ask why not and request to see photos or examples of work. Just as with all other realms of business, fenestration companies range from the highly professional to the amateur, so you should check a company's past performance. Also, don't be afraid to ask for customer references.  

Ask for a written quotation and agree on an exact price before signing: Through the 80s, many glazing companies gave the industry a bad name with high-pressure, door-to-door sales tactics, and extortionate pricing. Thankfully, the sector has cleaned up its act in recent years, but you should still ensure the company you hire clearly outlines the work's cost before starting on the job. You should also ask what contingencies the firm has if a job over-runs – and responsible for picking up any budgetary shortfalls.  

Check guarantees and warranties: As windows are open to the elements, normal wear and tear can be expected, but you should still request the company to define what guarantees, repairs, or warranty protection are included with your windows. 

Get multiple quotes and avoid signing anything on the spot: Most professional salespeople will try to push for purchase on the spot but avoid the temptation to sign contracts without first consulting other firms to get a range of prices. Conventional wisdom suggests that you should get a minimum of three quotes from different companies to allow you to compare prices and services when it comes to merchants.
