Working with another company

This sounds like a great opportunity for both you and the home remodeling company. As with any new business relationship, my advice would be to set a meeting with this person to set clear expectations about your services, pricing, and timelines. I'd express interest in helping each other grow your businesses and see if he would also be open to providing referrals or introductions to clients and people in the community. You could work out a commission or discount on future projects to the remodeling company based on the clients who sign up for a service plan with you. Lots of possibilities here. Good luck and congrats!

I am just getting into these types of mutually beneficial partnerships myself... here's what I'm doing if it's helpful:

We run a handyman and home improvement company, and I have a real-estate agent who is willing to add my marketing flyer and exclusive coupons I am making for her in her "new homeowner welcome packet" she leaves for her customers after she sells a home in our service area. In return, we've agreed to refer our customers to her when we identify a potential client for her (often we get "We're looking to fix our house up and get it ready to sell" requests, so it's mutually beneficial.

Companies that are in related businesses but not direct competitors can and should recommend each other, provided you are confident in the other company's work. At a plumbing company where I used to work, the owner had actually worked out several deals with other companies. We would often get asked by customers if we knew a good electrician, HVAC company, landscaper, carpenter, etc. The boss actually gave each technician a printed list of company names to share with customers as "We at ________ Plumbing recommend ________ Electrical. We've done a lot of projects side by side with them and they're professional, knowledgeable, and fair."

The idea was that ____________ Electrical was saying the same about us when their customers would ask them for a plumbing recommendation. There was no sort of formal deal, commission, or kickback, just the mutual benefit of knowing that someone out there was spreading your name. 

I'd recommend in your case exchanging a stack of business cards with your fellow business owner and having them ready in your work vehicle in case you're asked. Or even if you overhear Mrs. Homeowner remarking about how she'd love to replace that rickety old porch on the back of the house, that's a perfect opportunity to pipe up with "I know a carpenter who is very good. I can give you his card if you'd like to talk to him about pricing a job like that". 

I also like HandyMillerMan's idea about just including the card with the literature that his Realtor friend would be giving to the customer anyway. That's a great idea in his situation.

Construction and remodel cleans are awesome money makers.

Pricing - I usually go hourly on these as there a lot of variables, but oyu can also go in by the sq ft. Most places hope ro see prices around .35-1.25/sq ft for construction cleaning depending on the square footage. If the sq ft is smaller, the price per sq ft would be higher, and so on and so forth. 

Operations - There is a LOT of dust. The floors may require a swing machine. You'll often need a scraper for glass and to remove protective coverings and stickers. Get a scope of work for each project agreed upon, even if you have to write it yourself (Chat GPT is the **bleep** for this)

If all else fails I'd be happy to help you. Just reach out.
