"Bill is great to work with. He does everything. We actually asked him to give us an estimate on a paint job to do next spring, but while he was here, he pointed out problems with part of our roof, plus trouble with gutters that were funneling water to siding that was rotted. Itâ s all fixed and we are looking forward to working with him in the spring. It was all more expensive that we expected, but I think we got good value for our money."

"I posted on Angi and Matt responded immediately and was friendly and professional. He made an access entry from the original basement wall into my addition. There was little to no cleanup for me after! Job well done to Matt and Dickie. I highly recommend Smithtown Landworks."

"Once again and with the highest confidence, we hired Russell's Contracting to convert our back entrance into a more open, useful mudroom. As promised, they arrived on time on the expected date and started by sealing off the back entrance for dust. The demolition of the closet was first done, and then the rehab began. I was amazed at the level of detail necessary to make the new mudroom perfect. From fixing the ceiling to installing new walls, taping and sanding, painting, new baseboards, and moving the overhead light, it was fun to watch. Colby was professional, exacting, efficient, clean, and asked all the right questions to ensure we were happy with the result. The new mudroom is exactly what we wanted. In addition, we asked Russell's to help us figure out how to make our open staircase to the second floor safer. Keith, Colby, and Max designed and installed a custom-built, stair-to-ceiling railing system that looks great and provides the necessary safety we were looking for. They also made it removable to accommodate large objects up and down stairs. The amount of time they spent was crazy, and the amount of math they did to ensure it was plumb and solid was above and beyond our expectations. My house was built in 1933, and this railing system looks like it could have been original to the house. It is a masterpiece. Everyone at Russell's Contracting we have met and who has worked on our house has been exceptional. You can stop scrolling for contractors; call Russell's."

"They showed up on time each day, were very knowledgeable of the work they performed. Showed up for the quote when we scheduled the first meeting and we were very impressed with the overall experience. The deck they built was spot on and perfect for our needs. They did make some recommendations as to how it would look and work better for us and we went with their decisions and are so happy and impressed. They were very neat about their work and very easy to talk with. I would never use anyone else, and HIGHLY RECOMMEND them for whatever you need. So great to work with."

Egress Windows FAQs, answered by experts

Yes, you can install a bay window in an existing house. You’ll need to have a structural engineer draw up plans to add the necessary support to your exterior load-bearing walls and a general contractor to make the changes to the framing around the new wall opening. This will cost an average of $3,000. After that work is done, a window installer can set the new bay window in place.

The cost of window installation depends on several factors, including the window type, size, and frame material. Labor rates, the need for custom sizing, and any required structural modifications will also influence the final price.

Adding windows to a house is expensive. Budget roughly $5,800 to add a single window, and double or triple that to add two or three. In some cases, adding a single window can exceed $20,000, depending on the type of exterior wall, the size of the window, the type of window, local permit costs, and other factors.

Egress windows are typically required for basements with habitable space or living quarters. Not all basements or lower levels require egress windows. However, egress windows are required in homes with living spaces such as bedrooms and living rooms in a basement. The International Residential Code and International Building Code require sleeping rooms to have a specific size egress window. Check your local building codes to confirm the requirements in your area.

The cost to install a bow window can range from $1,500 to $15,000, with a national average of $3,900. The total price includes materials, which can cost between $1,200 and over $14,000, and labor, which typically adds $300 to $1,900. Several factors influence the final cost, including the window's size and frame material. For example, vinyl frames are the most budget-friendly option, while wood frames are more expensive. Custom features or energy-efficient upgrades will also increase the price. For comparison, a bay window installation typically costs between $1,000 and $7,000.
