Sunrooms are one of the most popular additions in Westchester — extending living space without the full cost of a room addition.
Cost by Type

|---|---|---|
| Screen room (no glass) | $8,000–$18,000 | Summer use only |
| Three-season room | $18,000–$40,000 | Spring-fall use |
| Four-season room | $40,000–$80,000+ | Year-round use, HVAC required |

📅 Get a Free EstimateGetting a Number You Can Trust
Estimating a project accurately takes more than a quick look. The cost is shaped by your home's existing conditions, the grade of materials you select, how accessible the work area is, and issues that only become visible once work begins. A trustworthy estimate comes from an in-person assessment, not a phone guess — guesses are how projects end up with change orders and budget overruns. We measure precisely, evaluate the real conditions, and hand you a written quote that separates materials, labor, and permit costs clearly.
A bid that's far lower than the rest deserves a closer look. In Westchester, suspiciously low pricing usually signals a corner being cut somewhere — inferior materials, an uninsured or unlicensed crew, or a low entry price designed to grow through change orders. The smartest approach is to gather several quotes and compare exactly what each one includes, line by line, rather than judging by the total.
Why We Itemize Everything
Itemized pricing puts you in the driver's seat. You can see precisely where a material change trims the budget and where cutting back would be a false economy. It also heads off the single most common home-improvement dispute: surprise costs. Every estimate we provide is free, conducted in person, and itemized down to the line so nothing is hidden and nothing balloons unexpectedly.
