Most of your traffic arrives with a photo of frost on the inside of the glass
Assume a phone, a cold room, poor patience and a screenshot already in the camera roll.
Winter visitors are not browsing. They have a symptom, they want to know whether it is fixable and what it costs to look at, and they are often comparing you against two other tabs already open.
Design the first screen for that state. Who you are, where you work, what you install, and one obvious next step. Anything that pushes the phone number below a video or a slider is costing you money.
Let people attach a photo in the inquiry form. It is the single most useful field on the page for this trade, because a picture of the opening tells your estimator more than three paragraphs of description.
Nothing on the first screen should require a second tap to understand. If the visitor has to scroll to learn whether you cover their town, you have already lost some of them.
