What we do
Three things, and they are the same three things we did in 1989
Optimise what is already there, build what is missing, and keep it open in winter. Most properties need two of the three; almost none need all of it at once.

Recent work
Photographs from our own jobs. We have not captioned these with towns, because the records that came with them do not say which town each one was in — and a made-up location under a real photograph is not worth the credit it would buy.
Where we work
Four towns, and each one builds differently
A lakefront lot in Mahopac, a ledge outcrop in Yorktown and a Woodbridge-loam slope in Cortlandt Manor are three different jobs wearing the same description. These pages say what changes.
Our yard is at 45 Sprout Brook Rd, Cortlandt Manor, NY 10567, which is why Cortlandt Manor gets the fastest response and why the snow route starts there.
What people say
These come straight from our review profile — we do not edit them and we cannot, which is rather the point.

A wall that's leaning, a patio you've been meaning to put in, a lot that has to be clear by seven in the morning. Call us, or send a couple of lines and we'll call you.
