When I land on your homepage there is nothing I can see that tells me what you do. I can see an image of a sofa, kitchen and a display cabinet but they look like stock images you downloaded off the Internet.
I scrolled down a bit in the hope I can find out what you do and I see two big boxes. One of them offers other services and the other is about a commitment. Neither of these tell me what you do.
You have a number of pages that detail the services you offer but none of these have any examples of your work.
You have a gallery but this is just random images - it doesn't tell what you did. And osme of the images look a bit iffy:

The testimonials page is just a form - so it looks like nobody has ever said thanks.
You don't have any stories on the site. You aren't telling me about the work you have done, the problems you encountered and overcame, where you have done things and for whom.
There is no evidence that you are a master builder.
You have a blog but this is just full of random articles (are you paying someone for this?). Bin the whole lot as they are pointless.
The contact page is mainly a map. Unless people can come round and say hallo you don't need a map. In any case, I can't use the map for directions because it's not linked to Google. Who is Jacques? Is he the runner, the secretary, the man with the DeWalt?
Some pages don't even exist:

There are no calls to action anywhere.
And the whole thing has been built on a $49 theme - and not done very well either. Google only scores you 57/100 on a page speed test. So the developer hasn't really done much to earn the money you paid them.
Sorry to be the bearer of bad tidings but it's not very good.
But it's all fixable. The key is the content. You need to tell me what you do on the homepage. Link from here to the specific service. On this new page provide more details with example of your work. Link to more pages that detail the project with pictures and descriptions. Add testimonials and link again to a page with all testimonials. Link from these back to the relevant project page.
And then find a better theme. One that doesn't have all the bolt on caggage you currently have.
The design of the site is far less important than the content and how you guide the visitor to the right page.
