Consumers: 5 reasons to outsource the window and door installation to a specialist

Installing windows and doors is an important task that requires expert knowledge and skill. While some people may opt to do it themselves or ask their builder to carry out the job, outsourcing the installation to a specialist can be a wise decision. In this article, we will discuss five reasons why outsourcing window and door installation to a specialist is a smart move.

Reason 1: Expertise and Knowledge

Years of Experience for Higher Quality Installation

When you outsource your window and door installation to a specialist like Sheerwater Glass, you will benefit from our years of experience and top quality service. Our team of experts have worked on all kinds of projects and are highly knowledgeable in their field, with several industry accreditations including FENSA, eco credentials, and outstanding customer testimonials. They know the ins and outs of the installation process and can ensure that everything is done correctly, giving you a guaranteed high quality of finish and fitting.

Specialists Have Access to High-Quality Materials

At Sheerwater Glass, our specialists use high-quality materials that are durable and long-lasting. Our expert knowledge and pride in our work mean we will only use high quality materials as opposed to cheaper run-of-the-mill products. These materials are designed to withstand different weather conditions, ensuring that your windows and doors remain in excellent condition for years to come, and that the installation process will run smoothly, achieving a fantastic end result.

Reason 2: Time and Cost Efficiency

Saves Time

Outsourcing your window and door installation to a specialist like Sheerwater Glass can save you a lot of time. Our experts work efficiently and can complete the installation process in a shorter amount of time than if you or your builder were to do the job. This means less hassle for you, without compromising on quality, workmanship or excellent service.

Saves Money

Outsourcing your installation to a specialist can also save you money in the long run. Thanks to our years of experience, we can complete your installation without any mistakes, saving you money on potential repairs or replacements. We will also specify the correct products and colours for your self-build rather than using bog-standard products, ensuring you achieve the design and practical effect you desire the first time around, for the best price.

Reason 3: Safety and Legislation

Specialists Follow Safety Protocols

Window and door installation can be dangerous, especially if you don’t have the right tools or experience. Our specialists follow strict safety protocols to ensure that the installation process is carried out safely. This means that you don’t have to worry about accidents or injuries occurring during the installation process.

Understanding of Legislation

As with any build project, there are a myriad of building regulations and planning rules you must abide by. As our specialists work on a range of different projects every day, they are thoroughly up-to-date with any relevant legislation, including the changes to Document L and Document F last year and how these affect new-build building regulations.

Reason 4: Warranty and Insurance


Outsourcing your window and door installation to our Sheerwater Glass specialists means you will receive a higher warranty than you would from a builder, including any aftercare required. This means that, in the unlikely case that anything goes wrong with your installation, our specialists will take care of it for you. You can also have peace of mind that any mechanical parts that we purchase are guaranteed to work, with operational warranties in place and a follow up service if required.


Our specialists also have insurance that covers any damages that may occur during the installation process. This means that you don’t have to worry about paying for any damages out of pocket.

Reason 5: Professional Results

Aesthetically Pleasing

When you outsource your window and door installation to us at Sheerwater Glass, you can expect professional results. Our team take huge pride in their work and strive to ensure that your windows and doors fit perfectly with the bespoke style and design of your Surrey home, working with you throughout your purchasing, installation and customer care journey.

Q: Why should I outsource my window and door installation to a specialist?

A: Whether it be uPVC windows, aluminium windows or timber windows, double glazing or triple, composite doors, bifold doors, patio doors or skylights, outsourcing your glazing services to a specialist like Sheerwater will ensure that the job is done correctly the first time and with the highest quality products, giving you peace of mind. Specialists like us have the necessary knowledge, experience and tools to install windows and doors safely and efficiently.

Q: Will using specialists for my window and door installation be expensive?

A: The cost of outsourcing your window and door installation will depend on various factors, such as the size of your project and the type of new windows and doors you choose. However, the investment is worthwhile as it will save you time and money in the long run by avoiding costly mistakes and ensuring the longevity of your windows and doors.

Q: Can I install windows and doors myself?

A: While it’s possible to install windows and doors yourself, it’s not recommended unless you have the necessary knowledge, experience, and tools. A poorly installed window or new front door can lead to air leaks, water infiltration, and other problems that can affect the energy efficiency and structural integrity of your home. It’s best to outsource this job to a specialist to ensure that it’s done correctly and to a high standard, with all the benefits of our outstanding customer service.
