Who We Are

A builder that thinks like an owner.

Most contractors build to finish. We build to last. Developing our own investment property taught us exactly what fails first, what buyers notice, and what quietly destroys a budget.

Monvestor Construction Group is a licensed general contractor working across Westchester County, New York, with selected investor work in New York City and nearby Connecticut. We handle ground-up construction, gut renovations, electrical, plumbing and exterior work. We also self-perform the trades most builders hand off, which is why our schedules hold and our finishes match the drawings. I am second generation in this trade: my father, Tony Monroy, has been building for decades.

The Founder

Jhon Monroy

Founder, Monvestor Construction Group LLC

I came up on my father’s job sites and now run Monvestor as my own branch of that work. His standard sits behind every job we take, and every one of them is mine to answer for.

When you call, you speak to the person who will be on your property.

What We Do

Five disciplines. One accountable team.

When the electrician, the plumber and the mason all answer to the same project manager, problems get solved on site instead of in an email chain.

New Construction

Ground-up custom homes and multi-family builds. Foundation, framing, systems and finish carpentry delivered on one schedule.

Renovations

Full gut renovations, kitchens, baths and additions. We open the walls, correct what is behind them, and finish to a sale-ready standard.

Electrical

Service upgrades, full rewires, panel replacements, generators and code corrections, all planned at rough-in rather than patched at the end.

Plumbing

Supply and waste rough-in, manifold systems, fixture sets, water heaters and repipes for both new builds and older housing stock.

Exterior & Masonry

Paver driveways, patios, retaining walls, steps, outdoor kitchens and full site work. This is the finish most builders subcontract away.

Not sure where you fit?

Tell us what you are trying to do and we will scope it honestly, including when the answer is that you do not need us yet.

The Difference

The trades most builders hand off, we perform.

Every handoff between companies is a place for a schedule to slip and a cost to appear. We removed most of them.

Who We Build For

Two very different clients. One standard of work.

For Homeowners

The home you actually wanted

Additions, gut renovations and ground-up builds for families who plan to stay. Clear scopes, real schedules, and a crew you can talk to.

For Investors

Numbers that survive contact

Scope-to-budget renovations for flips and rentals. We have carried our own deals, so we price the work the way you underwrite it.

How It Works

Four steps, no surprises.

01

Walk-Through

We visit the property, listen to what you want, and tell you plainly what is realistic on your budget and timeline.

02

Scope & Estimate

A line-item proposal covering every trade. No allowances hiding the expensive decisions until later.

03

Build

One project manager, our own trades, weekly updates and photographs. You always know what happens next.

04

Punch & Handover

We walk the job with you, close every item on the list, and hand over a property that is genuinely finished.

Rated 5 out of 5
Tony and his crew did an amazing job on our kitchen. They kept us in the loop the whole time and finished when they said they would. Couldn't be happier with how it turned out.

Safety was a big deal for us and Jhon didn't cut any corners putting in our new fire alarm system. The work was clean, he explained everything, and it passed inspection the first time.

Our renovation touched almost every room in the house and Tony managed it professionally from start to finish. Fair pricing, good communication, and the results speak for themselves.
