This is a relatively advanced DIY project due to the need for temporary support, and design of such a beam definitely requires an engineer or architect, unless you are willing to take your chances on the house falling down. Part of the cost is design and permitting, most of the cost is labor to install, and the beam itself is a few hundred dollars. The cost of designing and installing a beam is often several thousand dollars. ![]() Raising a 130 lb beam required use of a comealong and a pair of ladders. Installation was relatively straightforward, I needed to support the joists using two temporary walls (one on either side of the beam). The steel beam ended up being about 6 inches deep, weighed a total of about 130 lbs. I needed to do special calculations to make sure the basement beam would not be overloaded. I carried both support posts down to a main wooden beam in the basement. The beam needed to support overlapping joists, each joist approximately 14 feet long, spaced 16 inches on center, supporting a floor above. The total span was approximately 12 feet. I can share my personal experience installing a steel header that eliminated a wall between my kitchen and dining room. If anyone can assist with sharing their experiences or recommendations, it would be much appreciated. ![]() The total load the beam would hold is only the first floor of living space, plus the asphalt shingle roof. The floor joists currently rest on top of this beam and have a 12' length on each side. The footers under the vertical beams that would be supporting new 20' load bearing beam are 24"x24" according to the original home blue prints. The proposed beam would be dead center in the middle of house in the basement spanning 20'. The highest amount of snow we have ever gotten was about 2 feet. I have low headroom to begin with so this will play into which material to go with.ฤก Story Ranch house located in Long Island, NY. I want to have a rough estimate of what my options are in terms of the beam itself and cost whether to go with LVL, Glulam, or steel. The problem with this is that it would create a span of about 20' in between each vertical support beam. At the moment, I am finishing my basement and it would make a huge difference if I could remove two support beams in the middle of the basement. ![]() I attempted to search for this topic but I was not able to find anything.
