"Mr. Sullivan brought an assistant and they cleaned our Appleton 2-story Victorian home's gutters and repaired a spot damaged by an ice dam in last year's severe winter. They were pleasant and professional. I would recommend them for this work and will be calling them soon for another gutter cleaning.

Barndominium Builders FAQs, answered by experts

Whether you buy a prefabricated shed or build one depends on why you need it and where you stay. For instance, if a simple garden shed is what you’re after, it’ll be less expensive to buy one already built. But if you want a shed with windows, plumbing, and electric work, a custom-built unit might be more suited to your needs.

Your foundation contractor will first need to remove the topsoil and any vegetation within 4 feet of the area around the barn. They’ll need to ensure they have clear access to the site to begin excavation, after which they can begin construction.

A simple A-frame chicken coop can take as little as three hours to build, but a more substantial all-in-one coop to house a large flock can take four or five days to build. Consult a local handyperson or custom coop builder for a time estimate based on the specific details of your project.

Adding an extension or addition to your home costs more than a loft conversion in all but the rarest cases where the home's structural integrity is lacking. Because a home addition requires a new foundation section or significant structural upgrades to handle a cantilevered portion, the cost compared to almost any loft conversion is significantly greater for the same square footage.

Whether you should choose a flat roof or a sloped roof depends on your particular situation. Flat roofs tend to be less expensive to install. However, sloped roofs have longer lifespans and stand up better to heavy snow and other inclement weather.

Keep in mind that even a flat roof needs to have a slight slope, usually around 1/2 inch for every foot. If it is completely flat, water will pool and cause damage, either from weight or leakage or rot.
