Windows & Doors (uPVC & Metal)- 28 Jan 2026
Very unhappy with how things went with Angle Construction overall. Poor comms during the transaction was the first red flag - no communication for 2 days the moment money was sent, however afterwards received an apologetic call - parts ordered and arrived in due course. Andrei turned up, and got to work on removing the old gate, but then started shaving down the post without saying anything -we were told after that the posts were not level. Eventually he said the door would need to be cut, which we agreed to. The door and posts were both cut to fit, but massive gap left at the bottom, and only half of the door fittings and no handles were installed! In addition, where the door was cut and the wood shaved made, a lot of mess was left all over the garden furniture and patio floor. Shocked at the lack of care and professionalism. He was clearly agitated and in a rush to leave. We have a working back door, but it looks like a real botched job. Not happy, and I would not recommend.

Windows & Doors (uPVC & Metal)- 3 Sep 2024
wanted to have window film installed: red flag events on the day in chronological order: 1. arrived 2 hours late 2. advised that film be installed on the outside if the property but it can also be installed inside if i wished to do so. 3. borrowed scissors to cut the film 4. the first tint installed was cut jagged, not straight on the sides revealing light leaks of irregular patterns whilst bottom had a huge gap that they were planning to cover with another sliver of film. this was when i told them to stop what they're doing and not waste anymore of my time. 5. they demanded i pay £20 for their unprofessionalism, which i reluctantly did as i feared for me and my family's safety they used my job as training ground to install film on my windows. good luck to you if use them. We should be protected by MyBuilder from cowboys like these.

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.
