Customer Questions
Click on the common questions about windows to view our answers and if there's anything else you'd like to know we're just a short phonecall away - our phone number is at the top of the page.
What types of windows do you offer?
We fit high-quality double-glazed windows in a range of styles and finishes, all designed for energy efficiency and durability. Tilt & turn or casement are the most popular, cost effective windows but we can also supply & fit modern sash windows for period properties – ideal if you live in a conservation area or have a period property.
What's the difference between replacement windows and new construction windows?
Replacement windows are designed to fit into existing window openings, while new construction windows are used when building a new home or during major renovations where the wall framing is exposed. So for example, if you are adding an extension or changing the layout of your house for a new kitchen.
How can new windows improve my home's energy efficiency?
Double or triple glazing, and low-emissivity (Low-E) coatings all help improve energy efficiency. These features help reduce heat transfer, keeping your home warmer in the winter and cooler in the summer. We can discuss various options with you if this is a particular concern.
Which window styles should I consider for my home?
Popular styles include:
Casement: Hinged at the side and open outward.
Double-hung: Both sashes move up and down.
Sliding: Move horizontally along a track.
Bay/Bow: Extend outward from the home, adding space and light.
The cost for the different styles varies, as well as the different materials (such as uPVC, timber, alu-clad, composite etc). We can discuss the options with you to give you an accurate cost, keeping within your budget.
What should I expect during the installation?
We will need access to the windows so would appreciate it if you can move furniture away from this area beforehand. We will cover your floors and try to minimise as much as possible the disruption and mess involved with any building work. We pride ourselves on taking good care of your home and ensuring a tidy work space. If you have pets you may want to consider confining them to one room or even letting them stay with a friend or family member to lessen any stress.
How much will windows cost to supply & fit.
There are so many different options & sizes of windows and trims that our price list would be a mile long if we were to list everything here.
It will be much more accurate if we can talk through and meausure your home for our estimate. We will give you a written estimate which is very clear and also shows our terms & conditions for the order. The whole process is very quick and easy.
We would recommend that you get quotes from more than one company to compare. However it’s worth noting that price isn’t everything. We are not the cheapest and we are not the most expensive but we like to think our work is of a high standard and we like to go the extra mile for our customers so overall we are very good value for money.
