Great job from start to finish. Communication was excellent, Don and his assistant turned up bang on time and worked like trojans to get the whole job done in a day. Also came up with excellent solutions to practical problems and he is very pragmatic about finding ways to make things work. All in all, the work done has massively improved the saleability of our house. Highly recommended.

Overall the job completed was very satisfactory Ben was very willing to please as two things I was not satisfied with he rectified immediately. He was polite and thoughtful and kept the house clean and tidy as best he could. He was very mindful of my dog when he worked and kept her safe when he was using the front door. I would most definitely employ him again.

Decking- 3 Jun 2026
Anthony did a great job from start to finish. Having had a few quotes, some cheaper, I decided to hire Anthony for the job as his quote was fair, thorough and clear about the process, materials, time needed, I did not get this assurance from some of the cheaper quotes. He listened carefully to what I was looking to do and make some good suggestions to help achieve the look I wanted for my decking. Communication was clear at all times during the job. Once the job started, Anthony was punctual each day, organised and ensured the site was kept clean at all times. I am very happy with the decking and standard of work achieved. I would highly recommend Anthony and AJK Building and would definitely hire him again for any future jobs.

Windows & Doors (Wooden)- 8 May 2019
I wanted to have a window put in to a downstairs WC, and a rear window converted to French doors. Dean replied quickly to my initial phone enquiry and came round with his builder to do a quick survey of the job, measure-up, and check window/door style/colour. His quote for the French doors & window installation, plastering, tiling, and clean-up was very reasonable. On his suggestion we reused a window frame from the rear window for the WC window thus saving money. The French doors were to the highest spec and leading to sides panels matched exactly to existing window leading. Reglazing of WC window with frosted glass exactly matched existing front door frosted glass. Tiling in the WC reused the existing tiles which had been removed carefully so they did not break. Tiling job was excellent. Overall an excellent, quick, courteous, friendly, professional, job. Couldn’t be happier. Dean and his team, and their great can-do attitude removed all the stress I might have had getting this job done. I will be hiring Dean for other work around my house in the very near future.

Before you commit to a contract with a local Harpenden 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 Harpenden, and what qualifications do you hold?

A window fitter in Harpenden 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?

Harpenden 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 Harpenden 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 Harpenden may take anywhere from a day to several days, depending on the number of windows and the complexity of the project.

FAQ: Common questions about window fitters in Harpenden

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

Most Harpenden 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 Harpenden 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 Harpenden 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 Harpenden 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 Harpenden will be aware of local regulations and can advise you on whether planning permission is needed.

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

If you're looking for bespoke or custom window designs, a local Harpenden 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.
