If you have access to the underside you can screw another 2 x 6 along side of each existing 2 x 6 to add strength. If you do not have access, you would have to remove the flooring and sub-floor to do this.

What is cost of replacing the floor joists under the crawl space with hardwood floors in the house?

The job is difficult, very uncomfortable, strenuous, and time consuming. All the nails attaching sub-floor and hardwood floor to the joist will have to be cut, the joist cut out two at a time, and then new, full-length joists installed in place. Depending on the year the house was built, this can be almost impossible to do as they will have to be position diagonally and then forced perpendicular to the direction of the floor. Once the new joists are positioned and supported on either end, the task of re-attaching the floor to the joists is undertaken. This will have to be done precisely and skillfully from underneath without allowing the fasteners (screws) to puncture through the floor into the living space. Pre-applying construction adhesive to the top of the joists is effective, but adds another difficult step to the installation (all while in the crawl space). I operate in New England and would charge $60.00/hr for the un-pleasure of this job. Of course the size of the room dictates the length of the job, but you could count on $2500.00 in labor plus materials.


Why does upstairs shake when walking?

If your house is wood framed with wood joists, the shaking may be caused by floor joists being too small. This will cause the floor to sink whenever a person walks across the room. Floor joists should be size by an experienced carpenter, architect, or engineer to prevent movement.Another cause of floor movement may be insufficient bracing between the floor joists. This will cause sagging and twisting of the joists.There are several solutions that require the skills carpenter. New joists can be added beside the existing joists to strengthen the floor. Another option is to add one or more beams and columns in the room below the floor. Or blocking can be added between existing joists to add support.


How can I fix a sagging floor in an old house?

What is the cost to replace a rim joist?

In a typical home, the surface flooring (such as wood, carpet or vinyl) rests on a subfloor, which rests on joists -- a series of closely spaced parallel beams that support the floor or ceiling loads. Joists are usually supported by a sill (a long horizontal timber that's the lowest part of the framework and rests on the foundation) or a girder (a large beam that's the main support of the building). When replacing rotted floor joists it's important to be sure the girder and sill are still intact.Typical costs:If only a few joists are rotted primarily at the bottom, they can be repaired using a process known as "sistering" -- after the rot is cleaned away and the timber treated to prevent more problems, a new joist is laid beside the old one and fastened to it. Total costs will depend on the extent of the damage and the ease of access to the joists (through a basement or crawlspace), but in general sistering averages $100 -$300 or more per joist, and could run $1,000 -$3,000or more to repair a tilted, wavy or bouncy floor under an average room.If the floor joists are extensively damaged, it will be necessary to support the house with jacks while the joists are removed and replaced. In many cases, the sill may also be rotted and need replacing. Costs can run $10,000 -$30,000 or more for a typical home, depending on its size, the extent of the extent of the damage and the ease of access to install jacks and replace the timbers. If the damage is limited to just one section of floor joists, the project could run $5,000-$10,000.What should be included:Joists carry the weight of walls, furniture, people, appliances and anything else placed on the flooring they support. Usually wooden floor joists are 2"x8", 2"x10" or 2"x12" timbers -- their size depends on their length, the amount of "load" they're designed to carry and the building codes in effect when the house was constructed. The Family Handyman explains how joists work.If there is sufficient access through a basement or crawlspace, floor joists can be repaired or replaced without significant impact on the rest of the house. However, if there is limited access, all furniture and appliances must be removed from the affected area and the flooring and subfloor torn out. The Family Handyman explains how to "sister" damaged joists and HammerZone.com describes using a jack to raise a slightly sagging floor.Additional costs:Floor joists can be damaged by boring insects such as termites or extended exposure to water. Before you replace damaged floor joists, you must exterminate the insects or improve the drainage and ventilation so the problem won't reoccur. Costs will vary widely depending on the extent and nature of the original problem.Typically floor joists are repaired or replaced working from below, in a basement or crawl space. But if there's limited access to the joists, it may be necessary to work from above, removing the flooring and subflooring to repair or replace any damaged floor joists. Costs will depend on the extent of the damage and the type of replacement subflooring and flooring chosen.


How much weight can your floor hold?

all depends how the floor is constructed and the size of the joists, the span of the joists, thickness of floorboards. Is it a concrete floor. Is it a 'live' load like people of furniture or a 'dead' load like an unsupported wall. It the house an old building or of recent construction. A residential standard suggests 40lb per square foot. Needs confirmation though
