5 Things You Need to Know Before Renovating a Second-Hand Home to Make It Look New
Many people want to have their own home but may find the prices of new homes unaffordable. A popular option is to buy a second-hand home and start renovating the house to make it beautiful again. However, before starting to demolish, extend, or improve, new homeowners should know what to consider to make the renovation process easy, avoid complications, and stay within the budget set.
1. Study the legal requirements before renovating a second-hand home
Renovating a house, whether it involves repairs, modifications, or extensions, requires checking if a permit is needed, especially for work like adding a carport, an outdoor kitchen, or a storage room. If done without permission, it could result in imprisonment of up to 3 months or a fine of up to 60,000 Baht under the Building Control Act B.E. 2522, Sections 21 and 39/2. If the house only needs minor repairs, such as replacing existing materials with the same type without increasing the structural weight by more than 10% or expanding the area by no more than 5 square meters without adding columns or beams, it may qualify for an exemption from needing a permit.
2. Inspect the house’s structure and surrounding conditions
Before starting renovating the house, it is essential to check both the vertical and horizontal structures for issues such as settling, tilting, rust on steel structures, cracks, and water leaks, as well as the electrical and plumbing systems, to ensure that the renovation will not exacerbate existing problems and will help extend the life of the house.
3. Set a budget and choose a professional contractor
Renovating a second-hand home often comes with hidden costs, including repair costs, decoration costs, system work costs, and material costs. Always set aside a budget for contingencies and choose a contractor with expertise to ensure that problems are resolved in one go, leaving the house completed without frequent repairs.

4. Choose appropriate materials and paint colors for the house
Second-hand homes deteriorate over time, so it is necessary to replace worn-out materials or parts of the house with better new ones. Many people focus on changing for convenience in daily life, such as Smart Home systems, long-term electricity savings with solar panels, or cool house paint
, or switching to environmentally friendly, low-carbon materials that are of high quality and have a longer lifespan, such as products with environmental labels certified by green labels or carbon reduction labels. Although they may be more expensive, they are worth it when considering the benefits received in the future.
One important aspect to consider is choosing the paint color for the house, as it serves as a protective barrier that every home needs to withstand heat, sunlight, UV rays, seasonal weather conditions, as well as pollution and dirt. BEGER COOL paint is considered a cool house paint that addresses many concerns in every season, whether hot or cold, with the innovation of AeroTech combined with Ceramic Cooling technology.

5. Repair or refurbish old furniture to make it beautiful again
A renovated second-hand home may come with old furniture. If the old items are in good condition, it is recommended to repair them first to stay within the budget, especially metal furniture or wood, which can have the old paint stripped off and be repainted.
If it’s new furniture that may not meet our taste, it is advisable to choose new pieces based on the theme or color tone of the room to ensure they match as closely as possible. However, if there is a brilliant room design idea, homeowners can paint the room, decorate the theme, and incorporate various furniture to express their personality.
Precautions when renovating a second-hand home
Expertise and experience in home renovation are often lacking for new homeowners. Renovating a second-hand home means that if we undertake the work without knowledge or consulting experts, we risk damaging the house instead of enhancing it, wasting money and time rather than keeping within budget and finishing the house on time for move-in.
Therefore, homeowners should consult contractors or renovation experts before starting the renovation process, especially for structural work and various systems within the house that require expertise and assessment from experienced individuals. This will help ensure a beautiful home in good condition as desired and save money, keeping within budget.
An essential part of renovating house walls is repairing, preparing the surface, and painting the entire system. Primer and topcoat are necessary because old plaster walls that have aged over time will deteriorate and have a reduced lifespan, thus requiring long-lasting protection from various paint products to ensure durability, strength, and beauty that will last for many years, even if it is considered a second-hand home.
