"Steve and his crew far exceeded my expectations on the screen porch build they recently finished. The quality of the job is fantastic. On top of that, Steve was right on time for the first estimate meeting, to the delivery of the materials, to the start and finish dates of the project (2 days from start to finish. The price was fair and there were no surprises. Steve also recommended we use a composite material, called Azek to trim the job out. Gorgeous! You can stop looking and just hire Howland Home Services for your project. You will not be disappointed!"

"Overall it went pretty well.  They stared early and stayed late to make up time lost for rain.  They were very concientious about picking up every day.  John and his entire crew were very friendly and respectful. 

At first I wasn't very pleased with the number of visible seams in the flashing on the roof facing the driveway.  The roof is very "wavy" due to the settling of our ancient house and apparently the seams were unavoidable.  Everything has settled more and it is fine.  What is most important is that John talked to us about it and wanted to do anything he could to make sure we were happy with the job.

We would hire him again for work.  He seems to love what he does and he wants to make sure his customers are happy and it shows."

"I contacted Homemade Designs to get some guidance in decorating the family room in my new home. The plans took longer than expected which created stress for me as I was on hold with very little furniture in my family room as I waited to get suggestions. The furniture which can be purchased through the company is worth the wait if you want something different than what you see at all of the typical furniture stores.
I would recommend Homemade designs.

"When searching Angi / HomeAdvisor, T&K Renovations was one of the companies that came up in my search for a contractor to work on my home in Nags Head, NC. I was quoted by (4) contractors total. Thaad Page with T&K was one of them. What initially stood out was his communication. Mr. Page didnâ t just sling me a quote only for me to guess the details and outcome of the job. He took the time to explain to me his approach to each part of the job (some parts of it that required a bit of creativity). Thaadâ s excellent communication early on was a big part of my decision to hire him and that same level of communication continued throughout the project once he started it. The Job: T&K repaired a significant amount of wood root in my homeâ s framing, re-sided the home with cedar lap and then stained it with the stain of my choice. They also took on the challenge of straightening out a large lop-sided and twisted shed on the property that had parts of itâ s foundation failing (pilings). This existing shed also had a large dip in the roof that needed to be addressed and siding that was disintegrating. The shed was somewhat functional but it was a downright eyesore so I wanted it to be renewed and more functional. Once the shedâ s foundation was reinforced, the shed was then straightened, re-sided, and a new roof was installed. It was then stained. In addition, a new shed door was built and installed. T&K was very professional throughout the job and it was clear that they cared about doing a quality job and satisfying the customer. The new siding on the home looks great and itâ s now protected from the beatings of norâ easters & tropical storms that pummel coastal homes. The shed has been brought back to life and is now an asset to the property. Something worth noting: Thaadâ s original quote included a new door for the shed but he went the above and beyond a typical shed door and built me a beautiful heavy duty custom door from aged oak that he had. He went the extra mile and I really appreciated this. I highly recommend Thaad, John, Rich and everyone at T&K Renovations and plan on hiring them again for a couple of additional projects that I need to have done at my place soon. Thank you T&K Renovations!"

Basement Remodel questions, answered by experts

Renovations that add functionality or more comfortable floor space generally add the most value when remodeling your home. Attic or basement finishing can add floor space without altering the home's structure, saving you renovation money while adding valuable space. Smaller improvements, such as installing smart-home components or replacing entry doors and windows, also experience high ROIs. 

The most challenging part of finishing a basement is addressing moisture control. Basement waterproofing is an essential task that requires a professional’s skills and knowledge. If you don’t properly waterproof your finished basement, it’ll be vulnerable to dampness, water damage, and mold growth. Ensuring proper insulation and ventilation to combat these issues while meeting building codes adds complexity to your remodeling project.

The time it takes to finish or remodel a basement can vary significantly, ranging from a few weeks to several months or even up to a year. On average, the construction phase can take four to eight weeks, but the total project time can extend to three or four months when including planning and permits. The timeline depends on several factors, including the basement's size, design complexity, the scope of the work, and your contractor's availability. A more detailed breakdown for an average-sized basement might include: framing (3-5 days), electrical and rough-in plumbing (3-5 days), drywall installation (5 days), flooring (2-3 days), and final touches like painting and trim (about a week). If preliminary work like installing a waterproofing system or addressing structural issues is needed, the timeline could extend to six to twelve months. Factors like difficult access, material transport, and ventilation needs can also add to the project's duration.

Since DIYing a basement remodel isn't typically advised, there are some ways that you can still save money on this project without putting yourself in danger. Some ways to save money on a basement remodel include:

  • Painting walls yourself versus including in the cost of the remodel 

  • Installing light fixtures yourself

  • Choosing prefabricated fixtures, like cabinets, over custom ones

  • Choosing a budget-friendly flooring option, like laminate or vinyl flooring, and add rugs where necessary

Home improvements that increase value offer a high return on investment (ROI) and can enhance your quality of life. Upgrades to your home’s curb appeal often add the most value, with garage door replacement having one of the best ROIs at 93%. Other high-value exterior projects include replacing your front door, upgrading siding and roofing, installing a stone veneer, adding new windows, and landscaping. For interior renovations, a fresh coat of paint provides an excellent ROI. Major projects like a kitchen remodel or upgrading appliances and HVAC systems also add significant value, as potential buyers appreciate the peace of mind that new equipment provides.
