We recently had new upstair windows fitted to our property. The fitters arrived at 8.30 in the morning and left, having cleared up all the mess at 5.30pm. The guys were very friendly and did an excellent job.

Our Frequently Asked Questions

Here are some of our frequently asked questions by our customers.

A Sash Window is a type of window that is made up of one or two panels, also known as sashes, that slide vertically or horizontally. This is a highly modern mechanism, yet it gives off a timeless elegance that adds charm to any property. This is especially true in some areas of Kings Lynn, which is known to have architecture from historical eras. Nonetheless, Sash Windows come in a variety of colours, allowing you to complement any home and add significant character. 

Sash Windows are usually made from Timber. This is to provide the authentic, down-to-earth feel that wood often has. That being said, some opt for other materials, such as uPVC and aluminium. This is particularly due to the high resistance effects they have to corrosion and acid. This helps fight against rain, keeping them looking great no matter the weather. 


Excellent Ventilation

The ability to open up both the top and bottom of a window gives you perfect control over your airflow. This is particularly useful to prevent your home from becoming dry and stuffy and keep your lungs healthy with the fresh Kings Lynn air.  

Easy Repair

Whilst a lot of windows are unwieldy and often require replacements for the entire unit after an accident or a case of wear and tear, Sash Windows are more adaptable. Instead of taking the entire thing apart, you’re able to easily replace the specific areas of the window that are damaged. This makes the windows a favourite in Kings Lynn. 

Adds Value To Your Home

Sash Windows are almost always a net benefit to any home in Kings Lynn. With these windows, you will have lower energy bills, low hassle, and full control over ventilation. These qualities, alongside their stylish appearance, adds a lot of value to a property in the eyes of a prospective buyer. 

Klic Home Improvement’s Sash Windows come with expertly constructed frames. Within these frames are seals that bond the window tight. That being said, unless you opt for double or triple glazing, you will find that noise may still penetrate through the glass itself. On top of the energy efficiency of glazing, you will find that it also has properties within the glass that will block sound decibels from entering your home. 

Sash windows can last a long time with proper care and maintenance, although how long depends on a couple of factors. One of these is the material the frame is made of. Timber Sash Windows can last up to a century. Aluminium and uPVC can last up to 20-40 years.
