Cheapest Way to Build a House in Nigeria in [current_date format= 'Y']

The rising cost of living has made most Nigerians consider building a house rather than paying a monthly or yearly fee for rent. However, the economic downturn and the devaluation of the Naira has seen the cost of building a house in Nigeria skyrocket with most building materials doubling in price and leaving many Nigerians stuck and stranded with no hope of erecting their dream houses. Fortunately, you don’t have to break the bank when building your house. This article provides tips on how to build a house in Nigeria with little money. Building and completing your dream house on a tight budget would be as simple as getting the right design and the building at the right time.  

How to Build a Cheap House in Nigeria

1. Get a Solid Land The type of land you choose to build on will make a big difference in your budget. Building in swampy areas would mean you will require more sand to fill the foundation, thereby costing you more money. You can easily tell how solid land is by checking the soil and the surrounding areas or by having a professional inspect the site.   2. Look for Discounts While there are many factors that affect the cost of building a house in Nigeria, the main factor that should be considered is the cost of the building materials. Today, the cost of building materials like cement, plywood, iron rods, and granite are higher than they were a few years ago. Before settling on a supplier, consider quotations from multiple suppliers to ensure you pick the one you can afford. Also, look out for discounts on building materials before making a choice. It is, however, important to note that the prices of building materials vary and will depend on the brand producing the materials. A bag of cement of a particular brand may cost N3,000, for example, but another brand may sell that same bag for just N2,500. Of course, you also have to be conscious of quality.   3. Get the Right Contractor A contractor will handle and monitor the building process and should be the first person to consider when planning to build on a tight budget. While you might develop your own budget, estimations, and quotations yourself, you will require the contractor to make proper estimations. It is important to get a competent contractor to prevent wastage of building materials, delays, and mistakes in the building process.   4. Reuse Materials It is important that used materials are not just dumped for new ones but are reused to avoid wastage. This will also save cost and reduce your expenses, which are exactly what you are looking for.   Related Price of a Bag of Cement in Nigeria Today () Cost of Security Doors in Nigeria Kitchen Tiles Prices in Nigeria Cost of Window Blinds in Nigeria Price of Dangote Cement in Nigeria Cost of Wall Tiles in Nigeria   5. Build Slowly While most people would love to build and complete their house quickly, it is quite better to build much slowly to ensure you are able to raise funds as you spend through the building process.   6. Keep It Simple and Small Although you might want your house to look fabulous on the exterior and interior, consider toning down on the design while on a tight budget. Several structures like extra rooms, pillars, generator houses, high-quality finishes would have to be forgone or you will find yourself spending more than you can afford. Keeping a house small goes beyond forgoing extra bedrooms or multiple sitting rooms; it simply means reducing the size of the normal rooms you wish to have in the house. Reducing the sizes will cut costs on cement, sand, wood and many other building materials simultaneously.    7. Sell Used Materials Rather than burning or dumping them, you would simply sell the used materials and get some of your money back. You can reinvest this money into the building project.   8. Choose to Hire Hiring some building materials could be a more affordable option than purchasing them. You can speak to the contractor or supplier about the possibility of hiring these materials and also compare the costs before making your choice.   9. Exclude the Finishing The finishing is a post-building process that will require a lot of money and might even cost more than the pre-building and building process combined. While you would need to roof and plaster the house, you might want to exclude painting the house just immediately.  Although an unpainted house might not look really fabulous, it would save costs until you are able to recuperate and complete the building project. Other finishing projects like fencing the house would be paused for the meantime. However, this would be a bad decision to make if you live in an unsecured area.   10. Do Away with Unnecessary Labour While building your house, you will require the services of labourers like plumbers, bricklayers, carpenters, electricians, painters, scaffolders and more. However, many labourers like bricklayers would function as carpenters and painters, saving you the cost of hiring extra hands. Also, ensure you are not hiring too many labourers to engage in the building process.   Final Thoughts Obviously, building a house is no small task and the cost of building materials are on the rise. These tips will guide you to make the right decision and build a comfortable house for yourself and family. Remember to keep it simple. Other addendums will follow later on.

Why Does Stucco Crack?

[caption width="480" align="alignleft"]Image Credit: www.mcgarryandmadsen.com[/caption] This article was written by McGarry and Madsen Inspection and was published first on www.mcgarryandmadsen.com

Why Does Stucco Crack?

There are three types of stucco finish walls on Florida homes: stucco on concrete block, Exterior Insulated Finishing System or EIFS (also called synthetic stucco), and stucco on wood frame construction. Stucco over concrete block has limited problems compared to the other two, and EIFS already has well-known and documented moisture intrusion problems, along with lawsuits dating back to the mid-1990s. So let’s look at the defects found in the third type: stucco that is applied over a paper-backed metal lath on wood frame wall construction, which was especially popular in Florida during the building boom of 2004 to 2008.

When buckling, ripples and stains appear in stucco, like in the photo above, homeowners get worried. But the trouble begins with small cracks like the ones shown below, barely visible, that let water into the wall.

The inherent problem with stucco on a wood frame structure is that wood moves around—expanding, shrinking, and sometimes twisting—with changes in humidity. Wood is also somewhat flexible. Stucco, on the other hand, is comparatively stable and stiff, but it expands and contracts with changes in temperature more than wood. When you apply a stucco surface to a wood wall, there must be built-in details to keep the differing movement of the two materials from cracking the less-flexible stucco.

The Florida Building Code uses the ASTM C-926-06 specifications for the application of stucco, which refers to it by the more technically correct name of “Portland Cement-Based Plaster.” The specs are based on these five time-tested standards:The Florida Building Code uses the ASTM C-926-06 specifications for the application of stucco, which refers to it by the more technically correct name of “Portland Cement-Based Plaster.” The specs are based on these five time-tested standards:

1) THICKNESS Stucco should be at applied in three coats, at least 7/8” thick (not including any texture) to resist cracking.

2) FLEXIBLE EXPANSION JOINTS Placed at regular intervals along the wall, they absorb the expansion and contraction of the stucco due to temperature changes. These are also called control joints.

3) WEEP SCREED A weep opening at the bottom of the wall lets any water that penetrates the stucco drain out behind it, instead of getting trapped and rotting the wall framing. When a wood-frame second floor is built on a concrete block first-floor structure, the weep screed will be a strip located at the bottom of the second floor level.

4) CASING BEADS These wrap around anything that penetrates the stucco surface—such as windows, doors, and soffit returns—to provide a gap that can be caulked and prevents hairline cracks that will admit water into the wall.

5) DRIPS At any change of plane from a vertical to a horizontal under-surface of the stucco, a drip edge lets water fall off at the corner and not migrate sideways due to surface tension.

All of this differs dramatically in complexity from the installation of regular siding, which depends on simple down-lapping of smaller pieces of building material for waterproofing, and movement is absorbed by the numerous overlapping joints, plus caulk around doors and windows.

If any of the five anti-cracking measures are ignored, you will have a stucco problem. Maybe not immediately, because it takes a few years for the initial small cracks to let in some water, which rusts the steel lath, and opens the cracks further, letting in even more water...and so forth. But it will happen.

Here’s a listing of how each one of the five can be done wrong:

1) THICKNESS When the total of the three coats of stucco dips below 7/8-inch thick, those areas are more prone to cracking. Sometimes only two coats are applied, with not enough curing time between coats. Also, if the backing paper and lath is sloppily installed, it can create pockets of thin coverage.

2) FLEXIBLE EXPANSION JOINTS The total area of stucco between expansion joints should not exceed 144 square feet, with the additional restrictions that the joints not be more than 18 feet apart along the wall and a length-to-height ratio that does not exceed 2.5 to 1. The expansion joints should be tied to the metal lath only, not attached to the wall sheathing underneath, so that the joints can move independently from the wall structure. Metal lath that is continuous behind the expansion, connecting both panels, defeats the joint. Expansion joints that are placed too far apart or attached directly to the wall sheathing will also not do their job. A crack along the side of an expansion is an indication that it was likely not installed properly.

3) WEEP SCREED No matter how carefully stucco is installed, some small cracks will appear over time. Trapped water wets the wood structure and starts rot when there is no opening at the bottom of the wall or the opening is obstructed. Some weep screeds have protective tape over the drain holes that should be removed after installation and gets forgotten.

4) CASING BEADS Sometimes they are simply not installed. Without a groove to apply flexible caulk, cracked stucco along the side of a window frame is a common place for the stream of rainwater that runs down the side of a window to enter the wall.

It begins as in the photo above, but buckling stucco and staining follow over time. The photo below shows typical damage in the wall framing from this defect.

5) DRIPS They are not as aesthetically pleasing as a simple corner bead where vertical surfaces return back horizontally, but ugly water intrusion damage ensues if a 1/4” minimum drip edge is not installed. The photo below shows the rotted wood sheathing found under the stucco at the corner of an open porch with this defect.

[caption width="437" align="alignnone"]Image Credit: www.mcgarryandmadsen.com / Mark Cramer[/caption]

Other defects that can cause stucco cracking include: not enough fasteners securing the metal lath, undersize fasteners that do not penetrate deep enough into the wall sheathing, improper lapping of the building wrap to the weep screed, and not leaving the required 1/8” gap between sheathing panels. Because many of the defects that allow water entry are concealed by the stucco itself, they cannot be verified without digging into the wall. But their symptoms bloom and spread on the wall surface over time.

It usually takes five to seven years or more from time of construction to see clear signs of distress in stucco walls that are the result of defective stucco installation. But every stucco finish will develop a few hairline cracks, so we recommend checking for them at least once a year, and sealing the cracks with a masonry caulk.

Repainting the walls and touching up the caulking every 7 to 10 years is also a good idea, since paint and caulk are your first layer of protection from water intrusion. Because home builders occasionally claim that inadequate maintenance of the wall finish is a contributing factor in stucco failure claims from their customers, your diligent maintenance may have the added benefit of helping you secure your claim for damage to your home if it is due to defective stucco installation.

When the cracks multiply and get worse, in spite of your maintenance and repairs, we suggest calling a professional inspector for further evaluation. The one you choose should be familiar with the installation standards and have some experience in diagnosing stucco problems, plus carry a couple of moisture sensing tools, such as an infrared camera and an electronic moisture meter, in their tool bag.

If you are wondering why older homes with stucco walls don’t have the same severe cracking problems as outlined above, it is because most of them are stucco over concrete block. The block has a similar rate of expansion and contraction as stucco, and concrete block is more forgiving of a little moisture intrusion. It can absorb and dissipate through evaporation any small amounts of water that penetrate the stucco.

The thickness of stucco, along with sufficient curing time between coats, also makes a stronger surface, and older homes that are of similar stucco-over-metal-lath are more likely to have been done correctly.
