Windows & Doors (uPVC & Metal)- 20 Feb 2019
I am extremely pleased with Anthony and his team, they supplied and installed 3 secondary windows 6.4mm stadip sound glass within 2,5week . Antony was fast, effective , professional. So was his team who installed fast and well the windows. The windows look elegant and dont obtrude . You actually have to "look for them" to see that there are secondary glazing. The sound of the streets seems to have been covered by cotton...i can at last enjoy the sound of my clock! I cannot recommend Antony Etheridge highly enough

We recently had all of our old windows replaced with new ones, and we couldn’t be happier with the results. From start to finish, the team was professional, punctual, and courteous. The workmanship was excellent, with great attention to detail throughout the installation. The quality of the materials is outstanding, and the new windows have completely transformed the look and feel of our home. Everything was fitted perfectly, and the work was completed to a very high standard, leaving everything clean and tidy afterwards.

Windows & Doors (Wooden)- 27 Nov 2024
Piotr was such a pleasure to work with - incredibly kind and polite, always on time, great communication, flexible with my grumpy neighbour and above all, takes great pride in his work which is really reflected in the quality of the work. I was desperate to restore my original timber sash windows which I knew were in great condition but found every other sash company just wanted to replace them rather than spend the time restoring them. I've learnt so much about sash windows from Piotr and all I can say is I'm so grateful that I found him rather than going with a larger sash company! My original sash windows are now looking more beautiful than ever and are fit for purpose, completely draft proof and double glazed. If you're considering restoring or replacing your sash windows please speak to Piotr - I can't him recommend enough. A real master in his craft - thank you again Piotr!

What to ask a window fitter in Knebworth before hiring?

Before you commit to a contract with a local Knebworth window fitter, be sure to have a more detailed hiring conversation and ask questions like these:

How long have you been working as a window fitter in Knebworth, and what qualifications do you hold?

A window fitter in Knebworth should be able to outline their years of experience and highlight any industry qualifications, such as FENSA or CERTASS certification, which ensures they adhere to building regulations. These certifications show they are up-to-date with the latest window installation standards and legal requirements.

Do you offer a warranty for the windows and installation?

Knebworth window fitters should offer a warranty covering both the products and their installation. Expect at least a 10-year guarantee on the windows themselves and a 1- to 2-year warranty on the fitting. This gives you peace of mind that any issues, such as leaks or defective windows, will be addressed without extra cost.

What type of windows do you specialise in?

It’s important to know if the Knebworth window fitter has experience with the type of windows you’re installing, whether that’s uPVC, aluminium, timber, or sash windows. A professional specialising in your desired window type will be better suited to its installation and ensure the windows meet your needs for aesthetics, energy efficiency, and durability.

What is your estimated timeline for installation?

Expect a clear timeline that includes the date of the window installation and how long the process will take. A typical window fitting in Knebworth may take anywhere from a day to several days, depending on the number of windows and the complexity of the project. This helps you plan for any disruptions or access requirements to your Knebworth home.

FAQ: Common questions about window fitters in Knebworth

Do window fitters in Knebworth handle the removal of old windows?

Most Knebworth window fitters will include the removal and disposal of old windows in their service. However, it's always a good idea to confirm this in advance, as some fitters may charge extra for disposal, particularly if there are a lot of windows to remove.

How should I maintain the windows installed by a local Knebworth window fitter?

Maintenance will vary depending on the type of windows you have installed. For uPVC windows, regular cleaning with soapy water and checking seals is recommended. Timber windows require periodic re-treatment with wood preservative. Ask your Knebworth window fitter for specific advice on how to care for your windows to ensure longevity.

Do I need planning permission for a window fitter to install new windows?

In most cases, replacing or installing new windows in your Knebworth home does not require planning permission. However, if you live in a listed building or a conservation area, you may need approval. A window fitter in Knebworth will be aware of local regulations and can advise you on whether planning permission is needed.

Can a window fitter in Knebworth help with custom window designs?

If you're looking for bespoke or custom window designs, a local Knebworth window installer should be able to work with you to create the ideal solution for your space. They may collaborate with manufacturers or suppliers to produce windows that fit your specifications, whether it's for unusual shapes, sizes, or unique materials.
