Construction & property workTurnovers, concrete & site workBackflow testing & compliance

We build, repair, and look after property across Westchester County.

From a single day's repair to a job that runs for weeks — concrete and site work, unit turnovers, grounds and snow, and emergency callouts.

Unit turnovers, drywall and paint, concrete and generator pads, carpentry and exterior work — with the scope written down before anyone starts.

And when the annual backflow test comes due, we test on site, file the results with your water authority, and remind you before next year.

How we work

No surprises on the invoice. That's the whole idea.

Most complaints about contractors come down to the same few things: work nobody agreed to, materials nobody can account for, and a final bill nobody can explain. Here's how we handle each of them.

  • The scope is written down first

    What's included, what isn't, and what we're assuming — agreed before the work starts, so "I thought that was covered" never has to happen.

  • Materials at documented cost

    We keep the receipts and pass materials through at what they actually cost. Anything beyond that — a pickup, a delivery, a handling service — is named and agreed up front, never buried in a markup.

  • Extra work gets approved before it's done

    If something turns up outside the agreed scope, it's priced and approved as a change first. It doesn't quietly appear on the final invoice.

All six commitments, and how a job runs start to finish

How a project runs

From the first call to the last invoice

  1. 01

    Tell us about the work

    Call or send the details. We'll ask what you need done, where, and by when.

  2. 02

    We look at the job

    For anything beyond a simple call-out we come and see it, so the scope is based on the actual property.

  3. 03

    Scope and terms in writing

    What's included, what's excluded, how materials are handled, and the payment stages — agreed before we start.

  4. 04

    We do the work, and you can follow it

    A record of each day on site, changes approved as they come up, and invoices that match what was actually done.

Who we work for

One property or forty

The person who asks for the work, the person who owns the building, and the person who pays the invoice are often three different people. We keep that straight.

  • Homeowners

    Repairs, renovations, concrete and exterior work on your own property — with the scope written down before anyone starts.

  • Property managers

    Turnovers, grounds and snow, and the running repairs across a portfolio. One contractor, one number, and a paper trail per address.

  • Institutions & agencies

    Work that has to survive an audit: purchase-order and contract references on every invoice, and prevailing-wage and certified-payroll documentation recorded and packaged with the job.

FAQ

Common questions

Everything we're asked most often, grouped. Each group has more detail on its own page.

Construction & property work

More on this

What kind of construction work do you take on?

Everything from a one-day repair to a job that runs several weeks: grounds and snow, unit turnovers and interior repairs, concrete and masonry, generator pads, fire hydrant work, site preparation, carpentry and framing, and exterior improvements. If you're not sure whether something is in our line, call and ask.

Do you take small jobs, or only large projects?

Both. A single gutter clean or a light replacement is a normal job for us, and so is a multi-week turnover. The same process applies either way — it's just shorter.

Do you work for property management companies?

Yes — turnovers, grounds and snow, and running repairs across multiple addresses are a large part of what we do. The person who requests the work, the owner, and whoever is billed can all be different, and we keep those straight.

Do you do public or prevailing-wage work?

Yes. We can carry purchase-order, contract and project references through to the invoice, record worker classifications against the hours, and collect prevailing-wage and certified-payroll documentation with the job. We provide the records; we don't act as your compliance or payroll adviser.

Can you come out after hours or in an emergency?

We take emergency callouts, weather response, and work that has to be made safe or put right before an inspection. Call rather than sending a form for anything urgent — we'll tell you what we can do and when.

Do you also do the backflow testing?

Yes — it's our other service line. If we already look after your property, the annual backflow test on the same address is one more thing you don't have to arrange separately.

Scope, pricing & invoices

More on this

How do you decide what a job costs?

It depends on the work. Some jobs suit a fixed price, some are better on time and materials, and some are a mix of both. Whichever it is, we agree the basis in writing before starting rather than deciding at invoicing time.

How are materials billed?

At documented cost — we keep the receipts. If there's a pickup, delivery or handling service on top, it's named and agreed in advance so you can see exactly what it is. We don't bury a markup in the material price.

What happens if the job needs more work than we agreed?

We stop and price it as a change first. Out-of-scope work isn't billed until you've approved it, and your original scope and price stay visible alongside any approved changes.

Will I get an itemised invoice?

Yes. Each line shows the dates, quantities, rate and what it was for, and the supporting detail and receipts are available on request.

Do you take a deposit?

On larger jobs there's usually a payment schedule — a deposit, one or more stages as the work progresses, and a final payment. There's no fixed formula; the stages are agreed with you before the first invoice.

What if I have a question about a charge months later?

We keep a record of each day on site and of every cost against the job, so we can answer a question about your invoice later without guessing.

How do I know the work is actually finished?

Depending on the job that can mean photos, a punch list worked through to the end, an inspection result, or your sign-off. "Complete" should be something you can see, not just an invoice arriving.

Backflow testing

More on this

Is backflow testing required?

In most cases, yes. Your local water authority requires the backflow assemblies it oversees to be tested on a set schedule — often once a year — and tracks the due date for each device.

How often do I need a test?

Usually once a year — your water authority sets the schedule, and each assembly typically comes due about twelve months after its last passing test.

Do you file the results for me?

Yes. After the test we submit your results to your local water authority and send you the certificate, so you don't have to chase the paperwork.

What happens if I miss my due date?

An overdue assembly can lead to non-compliance notices from your water authority. We send reminders as your date approaches so it doesn't slip.

Which assemblies do you test?

The standard field-testable backflow assemblies — RP, RPDA, DC, DCDA, PVB, and SVB — across fire-sprinkler, irrigation, domestic, boiler, and pool systems.

What does a backflow test cost?

Pricing depends on the number and type of assemblies at your property. Request a test and our office will confirm the details with you.

How do I get started with a test?

Request a test online or give us a call. Our office follows up by phone or email with the available times.

Where we work

More on this

Where do you work?

Westchester County, NY, for both construction work and backflow testing. If your property is nearby but outside the county, call and ask rather than assuming — we would rather answer for your actual address.

How do I find out if you cover my address?

Give us a call and tell us where you are — we'll say yes or no on the phone rather than leaving you guessing.

Will you come out for a small job?

Yes. A single day's work at one address is a normal job for us — a gutter clean, a repair, a light replacement.

Do you charge for travel?

Customer invoices generally don't add travel time as labour. Where a job genuinely needs its own trips — a materials pickup, a delivery to site — that's a named service agreed with you in advance, not a surprise line.

Do you work at more than one property for the same customer?

Often. Property managers use us across a portfolio, and we keep each address's work, costs and paperwork separate so an invoice is always tied to one property.
