Not sure what you’re really looking for but here’s some stuff:
The logo changes dimensions as you scroll down.
Stick some quotes from customers saying what a good job you do on on there.
Stick your phone number front and centre on each page and say something like ‘Call now: <phone number>’
Create a ‘contact’ page of its own. Clicking ‘contact’ from any link on the site loads the homepage and scrolls down, it’s slow.
Search engine optimisation is all about copy. Put descriptions under images stuff like that. Make pages specifically about the terms you want to be found under.
Lack of prices might put people off. Maybe a ‘prices from’ link or something?
The photos are weird, like the diagonal lines are pixelated from something
